Track Character Injuries

River's AI helps you track all character injuries across your manuscript, checks for consistency issues, reminds you about recovery timelines, and ensures wounds have appropriate lasting effects on character actions.

Your protagonist gets shot in the shoulder during a fight scene. They gasp, clutch the wound, blood seeping through their fingers. Dramatic. Painful. Readers hold their breath. Two chapters later, your protagonist is in another fight, throwing punches, climbing walls, doing everything they did before. The gunshot? Never mentioned. The wound? Apparently healed.

Beta readers notice: "Wait, didn't they get shot two chapters ago?" "How are they using that arm?" "Shouldn't they be in the hospital?"

You're frustrated. It was just a plot device. The story needed to move forward. You didn't want to bog down the narrative with medical details. But readers are pulling out of the story, noticing the inconsistency, questioning the stakes. If a gunshot wound doesn't matter, why should they worry about your character in danger?

Here's what experienced writers know: Injuries don't have to slow down your story, but they do have to matter. You don't need medical textbook accuracy, but you do need consistency. When characters get hurt, show appropriate consequences. When they heal, show realistic timelines. When injuries disappear between chapters, you lose believability—and with it, stakes.

This guide will teach you how to write realistic character injuries: actual recovery timelines, how injuries affect character actions, common mistakes to avoid, and systems for tracking wounds across your manuscript so nothing magically disappears.

Why Injury Realism Matters

Stakes Require Consequences

If injuries don't matter, danger doesn't feel real. When your protagonist gets stabbed but fights at full strength next chapter, reader learns: wounds don't actually affect this character. Future danger scenes lose tension because reader knows character will be fine regardless.

But when injuries have weight—when that stab wound means character can't climb stairs without gasping, can't fight as well, needs help with basic tasks—suddenly danger matters. Readers fear for character because they've seen consequences.

Believability Grounds Your Story

Even in fantasy or sci-fi, readers need to believe in your world's internal logic. Inconsistent injuries pull readers out of story faster than almost anything else. Many readers have personal experience with injuries. They know how long broken bones take to heal, what sprains feel like, how concussions affect thinking. When you get it wildly wrong, you lose them.

Character Reveals Character

How your character handles injury reveals who they are. Do they push through pain? Complain constantly? Refuse help? Accept vulnerability? Hide weakness? Injury creates character development opportunities. Watching character adapt to limitations, struggle with reduced capability, or come to terms with permanent damage—this is compelling character work.

Realism Level Varies by Genre

Literary/Contemporary: High realism expected. Injuries have realistic timelines. Medical treatment accurate. Readers notice inconsistencies.

Thriller/Action: Moderate realism. Some dramatic license acceptable. Protagonist can push through pain during immediate crisis. But major injuries can't be ignored completely.

Fantasy/Sci-Fi: Genre-dependent. Magic or technology can speed healing—if established and consistent. But within your world's rules, must be consistent. Can't suddenly have healing potion when convenient if you've never mentioned them before.

Historical: Period-appropriate treatment. Research what medical care was available. Infections more common. Some injuries we'd treat easily today were fatal then.

The principle: Whatever realism level you choose, be CONSISTENT. Don't have character shrug off gunshot in Chapter 3 but be incapacitated by sprained ankle in Chapter 10.

Realistic Recovery Timelines

Minor Injuries

Bruises:
Timeline: 2-4 weeks to fully heal
Immediate: Pain, swelling, discoloration
Week 1: Peak pain, color darkens (purple/black)
Week 2-4: Color changes (green/yellow), gradually fades
Effect: Painful to touch, affects movement if on joint or muscle

Sprains (ankle, wrist):
Mild: 1-2 weeks
Moderate: 3-6 weeks
Severe: 6-12 weeks
Immediate: Pain, swelling, can't put weight on it
Treatment: Rest, ice, compression, elevation
Effect: Limited mobility, can't walk/grip normally
Reality check: Can't just "walk it off" in same scene

Cuts requiring stitches:
Stitches out: 7-14 days
Fully healed: 2-4 weeks
Scar: Permanent
Effect: Tender area, pulls when moving, scar tissue less flexible

Moderate Injuries

Broken ribs:
Timeline: 6-8 weeks to heal
Immediate: Severe pain, difficulty breathing deeply
Week 1-2: Extreme pain with any movement, laughing, coughing
Week 3-4: Still painful but bearable with care
Week 5-8: Gradually improves
Effect: Can't fight, can't run well, twisting torso excruciating
Reality check: Character can't have broken ribs and be in sword fight next chapter

Concussion:
Mild: 1-2 weeks
Moderate: Weeks to months
Severe: Months to permanent effects
Immediate: Confusion, possible unconsciousness, nausea
Hours after: Headache, sensitivity to light/noise
Days after: Cognitive fog, fatigue, irritability, difficulty concentrating
Effect: Can't think clearly, needs rest, symptoms worsen with activity
Reality check: Multiple concussions cause serious cumulative damage

Broken bones (arm, leg):
Timeline: 6-8 weeks in cast, then physical therapy
Immediate: Extreme pain, complete inability to use limb
In cast: Itching, muscle atrophy, frustration
After cast: Weak, stiff, needs strengthening for weeks/months
Effect: Limb completely out of commission
Reality check: Can't remove cast early because "need to fight"—bone not healed

Major Injuries

Gunshot wound:
Depends entirely on location and what was hit.
Shoulder: 3-6 months recovery, possible nerve damage
Abdomen: Life-threatening, requires surgery, months recovery
Chest: Often fatal without immediate medical care
Effects: Shock, blood loss, infection risk, severe pain
Reality check: Not "just a flesh wound" unless truly superficial graze. Bullets damage tissue, bones, organs. Exit wounds often worse than entry.

Stab wound:
Similar to gunshot—severity depends on depth and location.
Superficial: Weeks to heal
Deep/organ damage: Surgery required, months recovery, possible permanent damage
Effects: Blood loss, infection risk, pain, limited mobility

Severe burns:
1st degree: 3-6 days (like sunburn)
2nd degree: 2-3 weeks (blisters, very painful)
3rd degree: Months, skin grafts, permanent scarring, life-threatening
Effects: Extreme pain, infection risk, fluid loss, scarring, possible disability

Track My Injuries

Immediate Effects of Injury

Physical Responses

Pain: Sharp, immediate at moment of injury. Can be overwhelming enough to cause shock or unconsciousness. Adrenaline can mask pain temporarily (minutes, not hours). When adrenaline fades, pain hits hard.

Shock: Body's response to severe trauma. Symptoms include pale skin, clammy sweat, rapid pulse, weakness, confusion. Can progress to loss of consciousness. Requires medical attention.

Blood loss: Minor bleeding stops with pressure. Moderate bleeding requires medical care. Severe bleeding is life-threatening—character passes out from blood loss, can die without intervention.

Reduced function: Injured limb doesn't work properly immediately. Can't put weight on broken/sprained leg. Can't grip with injured hand. Can't see out of injured eye. Function may not return even after adrenaline.

Adrenaline: Superpower With Time Limit

Fight-or-flight response can let character temporarily push through injury. But it's temporary—minutes, not hours. And there's a crash afterward.

During adrenaline rush:
- Can ignore pain to some degree
- Increased strength and speed
- Heightened focus
- Keeps going despite injury

After adrenaline fades:
- Pain hits full force
- Exhaustion
- Shaking, possibly nausea
- Emotional crash
- Injury's full impact felt

Use wisely in fiction: Character can fight through injury to escape immediate danger. But show the crash afterward. They collapse. Start shaking. Pain overwhelms them. Can't keep going.

Lasting Effects and Complications

Physical Lasting Effects

Permanent scarring: Deep cuts, burns, surgeries leave visible scars. Scar tissue is tougher, less flexible. Can limit range of motion. May be disfiguring. Has psychological impact.

Chronic pain: Not all injuries fully heal. Old wounds ache in cold or damp weather. Nerve damage causes ongoing pain. May need pain management long-term.

Reduced mobility: Joints never quite the same after significant injury. Arthritis often develops in injured areas. Can't do things they used to. Range of motion limited. May walk with limp, favor one side.

Weakness: Muscles atrophy during healing. Injured area remains weaker even after healing. More prone to re-injury. Requires ongoing maintenance/strengthening.

Psychological Lasting Effects

Trauma/PTSD: Serious injuries can cause ongoing psychological effects. Nightmares about injury. Fear of similar situations. Hypervigilance. Anxiety.

Changed relationship with body: Loss of confidence in physical abilities. Fear of re-injury limits willingness to take risks. Grief over lost capabilities. Identity shift if injury changed what they can do.

Depression/anxiety: Frustration with limitations. Worry about future. Loss of independence. Social isolation during recovery.

Common Injury Mistakes

Mistake 1: Instant Recovery

Problem: Character badly injured in Chapter 5, fighting at full strength Chapter 6.

Example: Broken arm on Monday, sword fighting Tuesday.

Why it fails: Destroys believability. Reader knows bones don't heal overnight.

Fix: Either more time passes between chapters, or show character still affected—compensating for injury, in pain, fighting with limitations.

Mistake 2: Inconsistent Pain

Problem: Injury hurts when convenient for plot, forgotten otherwise.

Example: Wounded leg causes limp during emotional scene, but character runs fine during action scene.

Why it fails: Inconsistency pulls reader out.

Fix: If injury limits character, it limits them consistently. If they can run on it now, they could have earlier.

Mistake 3: No Functional Impact

Problem: Character has injury but it doesn't affect what they can do.

Example: Broken fingers but still typing, gripping sword, doing everything normally.

Why it fails: Injury becomes meaningless decoration.

Fix: Show how injury limits actions. Character has to adapt, ask for help, or choose not to do things.

Mistake 4: Magical Disappearing Wounds

Problem: Injury mentioned once, never referenced again.

Example: Character gets stabbed Chapter 10. Wound never mentioned after Chapter 11.

Why it fails: Breaks continuity. Readers notice.

Fix: Track injuries. Reference periodically. Show healing progression or lasting effects.

Mistake 5: No Cumulative Effect

Problem: Character takes beating after beating with no cumulative toll.

Example: Concussion after concussion, fight after fight, never slowing down.

Why it fails: Real bodies break down. Each injury makes character more vulnerable.

Fix: Show accumulating damage. Character getting slower, weaker, more desperate. Can't take as much as they used to.

Mistake 6: Hollywood First Aid

Problem: Using unrealistic treatment portrayed in movies.

Examples:
- Pulling out arrows or knives (causes more bleeding)
- Drinking alcohol to "disinfect" (minimal effect)
- Cauterizing wounds with hot iron (causes more damage)
- Sucking out venom (doesn't work)

Fix: Research actual first aid for injury type. Or keep treatment vague if not central to story.

Showing Injury Impact on Character Actions

Show Through Action Limitations

Don't tell: "His broken arm hurt."

Show: "He reached for the door with his right hand out of habit, then gasped as pain shot through his broken arm. Left hand then. Everything took twice as long."

Show Through Character Adaptation

Character with sprained ankle:

- Leans on furniture when walking
- Sits down whenever possible
- Asks others to fetch things
- Plans routes to minimize walking
- Frustrated by dependency

These adaptations show injury's reality without stating "ankle hurts."

Show Through Other Characters

"You look terrible."
"You should be in bed."
"Let me help you with that."
"Are you sure you should be doing this?"

Others' concern reinforces that injury is serious and visible.

Show Through Internal Monologue

"Every step sent sharp pain up her leg. Three more blocks. She could do three more blocks. Had to. No choice. But God, it hurt. Each step worse than the last. Just two more blocks now."

Internal experience makes injury visceral for reader.

Show Through Pacing Changes

Injuries slow characters down:

- Tasks take longer
- Need rest breaks
- Can't keep up with others
- Miss opportunities because too slow
- Arrive places late, exhausted

Tracking System for Injury Consistency

Create Injury Log

For each injury in your manuscript, track:

Character: Who is injured
Injury: Type and severity
Chapter: When it occurred
Cause: How it happened
Treatment: What was done immediately
Timeline: Expected recovery duration
References: Chapters where injury mentioned/shown
Residual: Lasting effects (scars, weakness, etc.)

Example entry:

Character: Sarah
Injury: Broken right wrist
Chapter: 8
Cause: Fall during chase scene
Treatment: Set and cast applied
Timeline: 6-8 weeks
References: Ch 9 (cast applied), Ch 12 (still in cast, frustration), Ch 15 (cast removed, weakness), Ch 18 (physical therapy), Ch 22 (healed but aches in cold)
Residual: Slight scar, weather sensitivity, occasional ache

Check During Revision

For each chapter, consult injury log:

- What injuries does character currently have?
- How should these affect their actions in this scene?
- Have I mentioned injury recently?
- Is enough time passed for improvement/healing?
- Am I being consistent with limitations?

Red Flags to Watch For

- Injury mentioned once then forgotten
- Character doing things injury should prevent
- Healing faster than realistic for your genre
- No reference to injury for many chapters
- Inconsistent pain/limitation (hurts sometimes, not others)

Final Thoughts: Injuries as Storytelling Tools

Injuries aren't just obstacles to overcome or plot devices to create drama. They're opportunities for character development, relationship building, and raising stakes. How your character handles pain, limitation, and vulnerability reveals who they are. How others respond to injured character deepens relationships. And realistic consequences make readers fear for your character in ways that no amount of action description can.

You don't need to become a medical expert. You don't need to slow your pacing with hospital scenes. But you do need consistency. Track your injuries. Show appropriate effects. Let consequences matter. Make healing take time.

When done well, injury realism grounds your story in physical reality even in fantastic settings. Readers believe your world because bodies work the way bodies work. They invest in your character because they see vulnerability and struggle. They fear for character's safety because they've seen that danger has real consequences.

The next time your character gets hurt, resist the urge to have them shrug it off by next chapter. Instead, show them adapting. Struggling. Healing slowly. Working around limitations. Being human. That humanity—that realistic vulnerability—makes them more compelling, not less. And it makes every fight scene, every chase, every moment of danger matter more, because reader knows: in your story, wounds are real.

Frequently Asked Questions

Can my action hero protagonist take more punishment than regular person, or is that unrealistic?

Depends on genre and how you frame it. Action thrillers allow some dramatic license—trained fighters DO have higher pain tolerance, better conditioning, know how to take hits. But: (1) Still feel pain, just push through better, (2) Still accumulate damage over time, (3) Still have limits—even tough characters break eventually. Show them being tough (gritting teeth, pushing through) but also show toll (exhaustion, slower reactions, needing recovery). What doesn't work: shrugging off injuries completely. Reader needs to see character is tough, not invulnerable. John Wick gets hurt and shows it between fights. That's the balance.

How do I handle healing magic or advanced medical tech in fantasy/sci-fi without making injuries meaningless?

Establish limits and costs: (1) Not everything healable (some injuries too severe), (2) Healing takes time/energy/resources (not instant), (3) Healing magic rare/expensive (can't use casually), (4) Healing has costs (exhaustion, magical debt, pain during process), (5) Repeated healing less effective (body develops resistance). Examples: Harry Potter—even magic can't regrow bones instantly (painful process, overnight). Star Wars—bacta tanks exist but characters don't always have access. Make healing available but not convenient. Injuries should still matter even if healing exists. Show character weighing whether to use healing (is injury bad enough to justify cost?).

What if my plot requires character to fight while injured? How do I make that believable?

Show: (1) Desperation—no choice, life or death situation, (2) Limitation—fighting worse than usual, slower, making mistakes, (3) Pain—grimacing, gasping, crying out when hit, (4) Adaptation—compensating for injury (switching hands, avoiding certain moves), (5) Adrenaline—short boost that carries them through but crashes after, (6) Consequences—injury worsens from fighting, needs medical attention after. What sells it: character obviously struggling, barely winning fights they'd normally win easily, paying price for pushing through. Don't: have them fight exactly as well as before injury. Injury must affect performance or it's meaningless.

Should I research every injury in detail, or can I keep it vague?

Depends on how central injury is to story. If injury is major plot point (affects character for chapters), research specifics. If minor (character sprains ankle, recovers off-page), can keep vague ('twisted her ankle, it hurt for a few days'). Rule: If showing treatment or recovery on-page, research it. If happens off-page, can be vaguer. Readers fine with 'the doctor patched him up' for minor wounds. But if character performing self-surgery or making medical decisions, better be accurate or readers with medical knowledge will notice. When in doubt: research basics (recovery time, major symptoms) and keep treatment vague unless you know what you're talking about.

How do I handle character with chronic condition or disability without being offensive?

Research and sensitivity readers essential. General guidelines: (1) Disability/condition isn't character's only trait, (2) Avoid 'inspiration porn' (disabled person exists to inspire others), (3) No magical cure unless that's explicitly what story is about, (4) Show both challenges AND character's competence/agency, (5) Don't make character bitter/angry stereotype, (6) Avoid 'suffering saint' stereotype, (7) Show accommodations and adaptations character uses, (8) Consult sensitivity readers with lived experience. Chronic pain, mobility issues, sensory disabilities—treat as part of character's life, affecting what they do but not defining who they are. Get it right by talking to people who actually live with condition.

What if I've already written my manuscript and realize injuries are inconsistent? How do I fix in revision?

Create injury log now for all existing injuries. Then: (1) Identify problems (injuries healed too fast, disappeared, inconsistent pain), (2) Decide fixes: extend timeline between chapters, add references showing injury still present, show lasting effects, or reduce severity of original injury. (3) Do find/replace for character name to locate all mentions, (4) Add injury references in chapters where currently absent, (5) Adjust character actions if doing things injury should prevent, (6) Check climax—if character fighting injured, show it affecting them. Takes time but fixable. Most authors don't catch this until revision. Better to fix now than have readers point it out in reviews.
