Key takeaways
- Chest pain, a sudden severe headache, one-sided weakness or numbness, trouble speaking, bladder or bowel changes, or a head injury with vomiting or confusion: emergency department, now.
- A sore, stiff, guarded lower back with no red flags, showing up a day or two after a crash or a hard shift, is the planned-exam pattern.
- The emergency department rules out the catastrophic. It usually does not write the treatment plan for the strain you walk out with. That is the clinic's job.
- An injury clinic that hears a red flag on the phone and sends you to an ER instead of booking you is the system working.
There are two doors, and picking the wrong one costs you either a night in a waiting room or something much worse. This chapter draws the line as plainly as a guide can without being a clinician. It is educational, not medical advice. When in doubt, the emergency department is the safer wrong answer.
The emergency door
Chest pain, a sudden severe headache, weakness or numbness on one side, trouble speaking, a loss of bowel or bladder control, or a head injury with vomiting or worsening confusion is an emergency room trip right now, not a call to a clinic.
For a back specifically, add these. New numbness or tingling in the groin, the inner thighs, or around the seat, the area a saddle would touch. New trouble starting or controlling urination, or a new loss of bowel control. Weakness in one or both legs that was not there before, a foot that drags, a knee that buckles. A back injury from a fall or a crash that leaves you unable to stand or bear weight. Severe back pain with fever. Back pain after significant trauma in an older adult or in anyone with brittle bones. The National Institutes of Health lists the warning signs that call for prompt medical attention in its back pain overview at niams.nih.gov.
If any of that is true, you are not reading the right site. Call 911 or go to the nearest emergency department. The metro has them in every direction, and an ambulance crew knows which one.
The clinic door
The pattern that belongs in a planned exam this week looks like this. A crash or a bad shift, a few hours of feeling mostly fine, then a back that stiffens overnight and is worst the next morning. Pain that is sore, achy, guarded, and worse with specific motions: getting out of the car, the first steps in the morning, turning to check a blind spot. Maybe some ache into a buttock or the back of a thigh. No numbness between the legs, no bladder or bowel changes, no leg weakness, no fever, no trouble standing.
That is the soft-tissue strain and sprain pattern, the most common kind of back injury after a low-speed hit, and the thing a chiropractic injury clinic examines every week. It still needs an exam, because the pattern is common but not the only thing that looks like it, and because a plan beats a guess. Missouri Injury Clinic's published auto injury lane is exactly this: diagnosis and a treatment plan after a crash. The first visit chapter covers what that looks like.
When the ER sends you home still sore
This is the gap the guide was built for. You went to an emergency department the night of the crash, which was the right call. They checked for the catastrophic, imaged what needed imaging, found nothing that required admission, and discharged you with a short instruction sheet and a recommendation to follow up. Two mornings later you can barely bend to tie a shoe.
The emergency department did its job. Its job is ruling out the things that kill or paralyze, not managing a strain over the next six weeks. The follow-up it told you to get is the planned exam. Bring the discharge papers and any imaging report to the clinic; they are the first page of your record, and the clinician will want to know what was already ruled out.
Where the doors are, relative to the rooms
The guide does not list hospitals, because an emergency is a 911 call, not a map search. What it can say is that the three clinic rooms are placed for planned visits: Tesson Ferry in south county, Hazelwood in north county, O'Fallon on the St. Charles side, all closed from 12 to 2 daily, all reachable on a morning call. The rooms chapter has addresses, phones, and hours. The clinic is a chiropractic injury clinic and is not an emergency facility.
The gray zone
Some readers are in between. A back that is bad but walkable, no red flags, but a nagging sense that something is off. The guide's rule for the gray zone: call the clinic in the morning and describe it honestly. A clinic that hears something belonging in an emergency department will say so. An injury clinic is built for planned care. If it sends you to an emergency room instead of booking you, that is the system working, not a wasted trip.
And if the gray zone turns into a red flag overnight, the order of operations flips. Emergency first. Always.

A sore, stiff, day-two back with no emergency symptoms belongs in a planned exam this week. Say crash if it was a crash, and bring the ER papers if you have them.
