SCI Red Flags: Is This an Emergency?
After spinal cord injury, some problems need action in minutes — not the next appointment. This guide is a quick scanner when something feels wrong and you are asking, “Is this an emergency?” It pulls together the highest-stakes warning signs that show up across many SCI complications.
This is not disaster or outage planning. For go bags, power failures, and evacuation, see emergency preparedness. This is also not the full treatment guide for any one condition. When you know which problem you are dealing with, use the deep-dive links at the end.
🚨 Red Flags — When to Seek Emergency Care
Call 911 or go to the emergency department right away if you have any of these:
- Autonomic dysreflexia (AD) that won’t settle — pounding headache, blood-pressure spike, flushing or sweating above your injury, after you have checked bladder, bowel, and skin. Injuries at T6 and above are at highest risk. Sit up. Lower your legs if you can. Do not lie flat (per PVA). See the autonomic dysreflexia guide for the full drill.
- Sudden breathing trouble — more shortness of breath, fast breathing, blue or gray lips or nail beds, thick yellow, green, or bloody mucus, or you cannot clear secretions even with your usual routine. If you use a ventilator or BiPAP, alarms, falling oxygen, or failed backup power are emergencies. See respiratory management and long-term ventilation.
- Chest pain when you breathe in, severe shortness of breath, coughing blood, a new cough you cannot explain, or a racing heartbeat — possible pulmonary embolism (PE). Very high risk after SCI (per PVA). See blood clots.
- One leg suddenly more swollen, warm, red, or blue-purple than the other — possible deep vein thrombosis (DVT). You may not feel calf pain. See blood clots.
- Fever, chills, nausea, vomiting, or feeling suddenly very unwell with urinary changes, a worsening wound, or breathing symptoms — possible UTI, pneumonia, wound infection, or sepsis (per SCIRE). See UTI prevention and pressure injuries.
- A new or fast-worsening pressure injury with spreading redness, warmth, foul odor, thick drainage, or you can see bone or tendon — infection can become life-threatening quickly.
- Sudden severe spasticity with trouble breathing or swallowing, a joint that locks up, fever with a tone spike, or baclofen pump withdrawal (sudden return of severe spasms, itching, or high temperature in someone with a pump). See spasticity management.
- New leg swelling, warmth, bruising, or a limb that looks bent or rotated after a transfer, fall, or with no clear cause — possible fragility fracture you cannot feel. A swollen warm leg can also be a clot. Get checked the same day. See bone health.
Tell the team immediately: “I have a spinal cord injury at [level]. I may not feel pain below my injury. I am at risk for autonomic dysreflexia [if T6+], blood clots, and complications you cannot see on a quick exam. Please take SCI-specific precautions.” Bring your wallet card and one-page medical summary if you have them (per Reeve).
Match Your Symptoms — Quick Decision Guide
Use the cluster that fits best. Each section names the emergency pattern and points to the full guide — not a substitute for it.
Head, blood pressure, or flushing above your injury
Think: autonomic dysreflexia — especially T6 and above.
Act in the first 60 seconds: sit up straight and lower your legs if you can. Loosen tight clothing and straps. Check bladder drainage first, then bowel, then skin pressure.
Go to the ER if pressure stays high, you have chest pain, trouble breathing, vision changes, seizure, or you cannot find the trigger.
Full protocol: Autonomic Dysreflexia
Breathing, chest, or cough
Think: respiratory crisis, pneumonia, PE, or ventilator failure.
Act: use your prescribed cough assist, suction, or ventilator troubleshooting while someone calls for help if symptoms are severe.
Go to the ER if lips turn blue, you cannot clear mucus, oxygen drops below your baseline, chest pain and shortness of breath come on fast, or you feel confused or unusually sleepy.
Full protocols: Respiratory Management · Long-term Ventilation · Blood Clots (for PE)
One leg looks or feels different
Think: blood clot or fragility fracture — both are SCI emergencies and can look alike.
Act: do not massage the leg. Compare both sides. Note when swelling or color change started.
Go to the ER if breathing or chest symptoms appear (PE), or the leg is clearly swollen, warm, bent, or new spasticity or AD appeared with it.
Full protocols: Blood Clots · Bone Health
Fever, chills, or feeling suddenly unwell
Think: UTI with kidney involvement, wound or pressure-injury infection, pneumonia, or sepsis.
Act: check temperature, urine appearance, any new or worse wound, and bladder drainage.
Go to the ER if fever comes with chills, vomiting, AD that won’t settle, confusion, or fast breathing — or you feel suddenly much worse than a typical cold.
Full protocols: UTI Prevention · Pressure Injuries · Respiratory Management
Spasms suddenly much stronger
Think: hidden problem below your injury — infection, fracture, skin breakdown, bowel or bladder issue, or baclofen pump problem.
Act: run the AD drill if you are T6+; check catheter, bowel, and skin; review pump alarms if you use one.
Go to the ER if breathing or swallowing is affected, fever is present, a pump may have failed, or spasticity is new more than a year after injury with no cause.
Full protocol: Spasticity Management
Skin wound getting worse fast
Think: deep tissue injury or spreading infection.
Act: stop pressure on the area, photograph if you can, do not use unknown creams on open tissue.
Go to the ER if you have fever, spreading redness, foul drainage, AD signs, or the wound looks deep or exposes bone.
Full protocol: Pressure Injuries
Urgent Same-Day Care (Not Always 911)
Some problems need same-day medical attention even when you are stable enough to travel by car:
- AD that settled but you are not sure what triggered it.
- Cloudy or smelly urine, new spasms, or low-grade fever without vomiting — possible UTI before it spreads.
- A pressure area that is not improving after two to three days of strict relief.
- One leg mildly different after a hard transfer — fracture or clot workup may still be needed.
- New pain, weakness, or numbness near your injury level — get checked the same day.
Call your rehab physician, SCI clinic, or urgent care and say you have SCI and which symptom cluster applies. If symptoms worsen on the way, go to the ER.
What Every Emergency Team Needs to Hear
People outside spinal cord care may not know SCI-specific risks. Say these plainly:
- Injury level and completeness — “C5 incomplete” or “T4 complete,” not just “paralyzed.”
- Bladder method — intermittent catheter, indwelling catheter, reflex voiding, etc.
- AD risk — if T6 or above: “I can have autonomic dysreflexia. Sit me up. Check my bladder and bowel before giving IV fluids or pain medicine that drops my blood pressure.”
- Clot risk — “I am at high risk for blood clots. Please evaluate for DVT and PE if I have leg or breathing symptoms.”
- Reduced sensation — “I may have a serious problem below my injury without normal pain. Please image or examine even if I say it doesn’t hurt.”
- Equipment — ventilator settings, baclofen pump, power wheelchair dependence.
Keep a wallet card and one-page summary with medications, allergies, equipment, and emergency contacts. The emergency preparedness guide covers what to pack. Reeve wallet cards on AD, clots, and sepsis are worth carrying (per Reeve).

Printable One-Pager Notes
- Target length: about 900–1,400 words — scannable bullets, not long prose.
- Keep the 🚨 Red Flags block and the symptom-cluster table in the upper half of the printed page.
- If your printer drops the emoji heading, write “RED FLAGS — EMERGENCY” at the top by hand.
- Pair this sheet with your wallet card and the emergency preparedness go-bag checklist. This page is when to act; that guide is how to prepare.
When something feels wrong, match your symptoms, act on the first cluster that fits, and escalate early. Many SCI emergencies are treatable when caught fast — especially AD, clots, infections, and fractures you cannot feel.
