Key takeaways
- Chest pain, a sudden severe headache, one-sided weakness or numbness, trouble speaking, loss of bowel or bladder control, or a head injury with vomiting or worsening confusion is an ER trip now. Call 911.
- The emergency room rules out what can kill you. It is not built to manage the three weeks of neck and concussion care that follow.
- An injury clinic is built for planned care: an exam, findings, a written plan, and the follow-through.
- Going to the ER first and the clinic second is the normal order after a serious crash, not a detour.
- If a clinic sends you to the ER instead of booking you, that is the system working.
Every page on this desk carries the same short list in the same words, because the list is the only thing on the desk that cannot wait for a second read. 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. If any of those describes you or the person next to you, stop reading and call 911. This page is for everyone else, and for the same people a week later.
What the emergency room is for
The ER exists to find and treat the injuries that threaten life or limb in the next hours: bleeding in the skull, a fractured spine, a collapsed lung, internal bleeding, a heart event masquerading as crash pain. It has imaging, surgeons, and the authority to admit you. When the symptoms on the list are present, or when the crash was violent enough that they might be, the ER is the only correct door. Nobody on this desk will ever talk you out of it.
Rollovers, high-speed highway crashes, crashes with airbag deployment, any loss of consciousness, any inability to get out of the car on your own, and any crash involving a pedestrian or a motorcycle are the kinds of events where the ER comes first without a second thought, whether or not the list applies yet.
What the emergency room is not built to do next
Here is the part people are surprised by. An ER visit after a crash very often ends with clear imaging, a diagnosis of a sprain or strain, a prescription, and instructions to follow up. That is not a failure. It is the ER doing its job: ruling out what can kill you. What it cannot do, and is not staffed to do, is manage the three weeks that follow: the exam that finds which structures are loaded, the written plan, the follow-up visits that track whether the plan is working, and the concussion rehab if the head is in the picture.
The follow-up instruction on the discharge paper is real. It is pointing at the second building.
What the injury clinic is for
Missouri Injury Clinic is built for planned care. Its auto injury lane, as published on its own site, is diagnosis and a treatment plan after a crash. Its TBI and concussion lane names its tools: vagus nerve stimulation, neurofeedback, Alpha Stim, sensory motor integration, exercise with oxygen, oculomotor rehabilitation, and cognitive rehabilitation software. Its sports injury lane is return-to-training care. All three lanes are behind all three doors, in Hazelwood, on Tesson Ferry, and in O'Fallon.
Missouri Injury Clinic publishes its auto injury lane as diagnosis and a treatment plan after a crash. A crash exam at any chiropractic injury clinic typically gets there through a history and an exam of how the neck and back move. Bring the ER discharge paperwork if you have it; it is part of the history, and the clinician should see what was ruled out before deciding what to examine. The first visit guide has the rest.
Discharged and still hurting? The ER ruled out the emergency. The clinic handles the week after. Bring the paperwork.
Start with an exam →The middle cases
Most crashes are not on the list and were not violent. The car is drivable, nobody lost consciousness, and the only symptom is a neck that is stiffer than it should be. That is a clinic exam inside the week, not an ER visit, and the ER will tell you the same thing if you go. The honest gray zone is the head. A headache that is getting worse rather than better, new vomiting, increasing confusion, or a person who is hard to wake is the list, and the list is the ER. A headache that is steady, a fog, light sensitivity, and trouble with screens is a concussion question for the clinic's TBI lane. The concussion guide goes deeper. When you cannot tell which side of the line you are on, the ER is the safe side.
Where each is, across the metro
The metro's hospitals cluster along its main corridors, and most readers know the one nearest them. The injury clinic's three offices sit on the arterials that feed those corridors: Hazelwood at 14 Village Square Shop Ctr near the 270 and 170 interchanges in the north; Tesson Ferry at 11144 Tesson Ferry Road, Suite 200, on the road that south county uses to reach everything; and O'Fallon at 2163 West Terra Lane off I-70 in St. Charles County. From any hospital in the metro, one of the three is a reasonable drive for a follow-up, and the offices page says which.
If a clinic sends you to the ER
It will happen sometimes. An office takes your call, hears a symptom on the list, and tells you to go to an emergency room instead of booking you. That is the system working, not a wasted trip and not a rejection. Go, get cleared, and call the office back with the discharge paper in hand.
What this page is not
It is not a diagnosis and it cannot tell you which side of the line you are on tonight. It is a description of two buildings and what each is for. Everything on this desk is educational, not medical advice, and is published as advertising for Missouri Injury Clinic. When in doubt, the emergency room is the right doubt.
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.
