Most crash injuries that were going to hurt are hurting within three days, because soft tissue injuries typically peak two to three days after impact rather than on the day itself. Some take a week or more — nerve symptoms, headaches and jaw pain often arrive late. This page covers when each kind of symptom tends to appear, which ones need emergency care whenever they show up, and why the gap between the crash and the first visit is worth closing.
Same-week appointments are usually available.
Soft tissue injuries typically peak two to three days after impact, not on the day itself — which is why so many people walk away from a collision feeling fine and wake up on the third morning barely able to turn their head.
Some take longer. Nerve symptoms and headaches can take a week or more to declare themselves. A few problems announce themselves much later, when the injured tissue heals in a way that keeps irritating something.
So the honest answer is: usually within seventy-two hours, sometimes a week, occasionally longer. The more useful question is what to do about that gap.
Three things are happening.
Adrenaline. In the minutes and hours after a crash your body is flooded with stress hormones that raise your pain threshold. They are doing their job. They also mean the assessment you make of yourself at the roadside is not a reliable one.
Inflammation takes time. A strained ligament or muscle does not swell instantly. The inflammatory response that produces the stiffness and aching builds over a day or two and peaks around forty-eight to seventy-two hours.
Guarding. After an injury the surrounding muscles tighten to protect the area. That protection is useful on day one and becomes a problem by week two, when the stiffness it creates is itself generating pain.
Immediately to a few hours. Obvious injuries — fractures, cuts, anything involving a head strike or loss of consciousness. These need emergency assessment, not an appointment.
One to three days. The most common window. Neck and upper back stiffness, headache at the base of the skull, mid-back and rib soreness, low back pain, shoulder pain from the seatbelt.
Three days to two weeks. Symptoms that were masked by the more painful ones become noticeable. Numbness or tingling into an arm or hand. Jaw pain. Dizziness or a foggy, off-balance feeling. Difficulty concentrating or sleeping.
Weeks to months. Pain that plateaued and stopped improving, or a problem that keeps returning with ordinary activity. This is usually not a new injury — it is the original one healing into a pattern that keeps getting provoked.
Do not wait for an appointment for any of these:
Two reasons, and they pull in the same direction.
Clinically, an injury assessed early is easier to treat than one assessed after six weeks of guarding and compensation. The tissue is the same; the surrounding pattern is not.
For the claim, a gap between the collision and your first medical visit is the thing insurers point to. It is a common argument, and it does not require any bad faith on your part — it just requires a gap in the record. Being seen early closes it.
That is the practical case for an examination in the first few days even when you feel broadly fine. It is not that something is necessarily wrong. It is that “nothing was wrong on day two” is a far more useful thing to have documented than nothing at all.
Care after a crash follows the same ladder as other musculoskeletal injury, with the documentation running alongside it.
Chiropractic first, for most crash injuries. Restoring movement to the neck and mid-back segments that have locked up is what reduces the day-to-day symptoms fastest. Every Mountain View Pain Center chiropractor is trained in whiplash and auto-injury care.
Physical Therapy alongside or shortly after. Rebuilding the strength and control of the neck and trunk is what keeps the improvement. It is also the part most often skipped, and the most common reason someone is still symptomatic six months later.
Acupuncture where muscle tension, headache or nerve irritation are a large part of the picture.
Pain Management when symptoms persist or when nerve pain is prominent — a physician review, and where appropriate targeted image-guided injections.
Imaging when the examination calls for it, not by default.
Billing. Care after a collision can be billed to med-pay, to a health plan, or held on a lien against the claim, so treatment does not have to wait for the claim to resolve. We check the route before treating.
Transportation. Medical transportation is available for accident patients and can be billed to the lien, so getting to appointments is not the thing that ends a course of treatment early.
Records. Pain Management, Chiropractic, Physical Therapy and Acupuncture sit on one chart, so the record of your treatment is a single file rather than letters gathered from separate practices.
Referral. Not needed for any of our services.
Treatment and the claim are two separate things. We handle our side so you can be treated while the rest is still open.
If an attorney is already involved, bring their contact details and we will work with their office directly: treatment records, imaging and the notes that document the injury. If you do not have an attorney, you do not need one to be seen here.
Bring your claim number and the adjuster’s name if you have them. If you do not have them yet, come anyway and we will work it out with you.

It is worth it. Soft tissue injuries typically peak two to three days after impact, so feeling fine at the roadside tells you less than it seems to. An early examination also documents your condition at the start, which matters if symptoms appear later.
There is no clinical cut-off — people are treated months afterwards and still improve. The earlier the assessment, the simpler the problem usually is, and the cleaner the record.
Adrenaline raises your pain threshold immediately after a collision, and the inflammation that produces stiffness builds over a day or two. The third morning is when both of those have turned against you.
Yes, particularly nerve symptoms, headaches and jaw pain, and symptoms that were masked by a more painful injury. New or worsening numbness or weakness should be assessed promptly rather than watched.
Usually, through med-pay, a health plan, or a lien against the claim. We check which applies before treatment starts.

Yes. After a collision we bill auto med-pay directly, or we hold the lien ourselves, so you are not paying out of pocket while the claim is open. Benefits are verified before your first visit rather than after it.
Your own uninsured or underinsured motorist coverage may apply. In Colorado insurers must offer medical payments coverage and it applies unless you rejected it in writing; in Arizona it is optional. We check what your policy actually includes before your first visit.
Yes. We coordinate with your attorney throughout treatment and send records to their office. If you do not have an attorney and want one, we can help you find one.
Yes. Medical transportation is available for accident patients, and it can be billed to the lien.
