Quick answer: whiplash usually feels like a stiff, aching neck that is worse when you turn your head, often with a headache that starts at the base of the skull, pain or tightness across the shoulders and between the shoulder blades, and sometimes dizziness, jaw pain, or tingling into an arm. Symptoms typically appear 24 to 72 hours after the crash, not at the scene. Most cases are soft tissue and joint strain that respond well to early, gentle, active care. A few symptoms mean you need an emergency department first; those are listed below.
Whiplash is a mechanism, not a diagnosis. In a rear-end collision the body is pushed forward by the seat while the head lags behind, forcing the lower neck into extension and the upper neck into flexion in a fraction of a second. Then the whole thing reverses. The muscles cannot react that fast, so the load lands on the ligaments, the small facet joints at the back of each vertebra, the discs, and the joint capsules. The resulting cluster of symptoms is called whiplash-associated disorder, and it is graded from I (pain and stiffness only) to III (nerve signs such as weakness or reflex changes). Most people I see are grade I or II.
Adrenaline blunts pain for hours after a crash, and the inflammatory response in strained tissue builds over one to three days. So the typical story is “I felt fine, then I woke up on Thursday and could not turn my head.” That delay is normal and well documented; it is not a sign you are imagining it or exaggerating. It is also why I tell people to be examined within 72 hours regardless of how they feel at the scene. The timeline is in what to do after a car accident.
Those are the criteria emergency departments use to decide who needs a CT of the neck before anything else. If you have any of them, go. If you are cleared, I pick up from there. For everyone else, imaging is decided by the exam, not by default; my guide on X-rays and MRIs explains why.
The evidence here is unusually clear. Early, gentle, active movement produces better outcomes than rest. Soft collars and bed rest, which used to be standard advice, make recovery slower and increase the chance of long-term pain. Reassurance and a plan matter too: people who understand that most whiplash recovers, and who are given things to do, recover faster than people who are frightened and told to wait. The treatment side is staged: calm the inflammation and guarding first, restore range of motion, then strengthen so the neck stops relying on guarding.
After a crash I see you the same day when at all possible, including Sundays. The first visit is 45 minutes: a detailed history of the collision, range of motion, orthopaedic and neurological testing to grade the injury and rule out the red flags above, and a decision about whether an MRI needs to come first based on your symptoms.
If the exam is clear, treatment starts that day and it starts gently: heat and electrical stimulation to settle guarding, low-force mobilisation of the stiff segments, soft tissue work on the muscles that are holding on, and two or three home movements. No forceful adjusting of an acutely inflamed neck. As the inflammation settles over the first week or two, I bring in full adjustments and start strengthening. Follow-ups are 30 minutes.
If you do not have an attorney and the crash was not your fault, I connect you with a local San Diego personal injury attorney at the first visit so the insurance side is handled while you heal; care is available on a lien with nothing out of pocket. All of that is on my car accident injury page.
What does whiplash feel like?
A stiff, aching neck that is worse turning the head, often with a headache starting at the base of the skull, shoulder and upper back tightness, and sometimes dizziness, jaw pain or arm tingling. Symptoms usually appear one to three days after the crash.
How soon after an accident do whiplash symptoms appear?
Typically within 24 to 72 hours, once adrenaline wears off and inflammation peaks. Feeling fine at the scene is common and does not mean you are uninjured.
Can you have whiplash from a minor fender bender?
Yes. Most whiplash injuries occur in low-speed collisions. The forces on the neck are much higher than the damage to the car suggests.
Should I wear a neck brace for whiplash?
No. Soft collars and rest slow recovery and increase the risk of long-term pain. Current guidelines recommend early, gentle, active movement.
When should I go to the ER for whiplash?
If you have a worsening severe headache, vomiting, confusion, loss of consciousness, spreading numbness or weakness, trouble speaking or double vision, inability to turn your head 45 degrees, or bladder or bowel changes. Otherwise a same-day exam with a provider who treats accident injuries is appropriate.
