Whiplash is a neck injury caused by a rapid back-and-forth motion of the head, most often in a rear-end collision. The soft tissue in the neck gets stretched beyond its normal range in a fraction of a second. Adrenaline routinely masks it at the scene, which is why symptoms commonly appear a day or several days later, and why 'I felt fine' is not evidence you were uninjured.
Symptoms, and When They Show Up
- Neck pain and stiffness, often worst on waking the next morning
- Headaches, usually starting at the base of the skull
- Reduced range of motion — hard to check your blind spot
- Shoulder and upper back pain
- Dizziness, fatigue, or trouble concentrating
- Tingling or numbness into the arms
Delayed onset is the rule rather than the exception. It is entirely normal to walk away from a collision, decline the ambulance, and wake up two days later unable to turn your head.
Low Speed Does Not Mean Low Force
Vehicles are engineered so the frame absorbs and redistributes impact. A collision that leaves barely a mark on the bumper can still transfer substantial force through the occupant's neck. The damage to your car is a poor proxy for the damage to you, and it is worth knowing that before anyone tells you otherwise.
Why Untreated Whiplash Comes Back Years Later
Soft tissue heals, but it heals with scar tissue that is less elastic than what it replaced. If the joints were left restricted while that happened, the neck sets into a compromised pattern. People routinely turn up a decade after a crash with chronic neck pain or headaches that trace straight back to it.
How Dr. Hansen Treats It
The exam establishes what actually moved and what is restricted now. Treatment restores motion to the affected joints before the tissue heals around the restriction, using specific adjustments matched to how acute the injury is — including gentle, low-force upper cervical technique where the top of the neck took the brunt of it.

Frequently Asked Questions
How soon after an accident should I be seen?
As soon as you can, even if you feel fine. Early documentation matters clinically and for a no-fault claim, and early treatment is meaningfully easier than treating a neck that has already healed stiff.
Can I have whiplash if my car was barely damaged?
Yes. Vehicle damage and occupant injury correlate poorly — modern frames are built to absorb impact, and force still transfers through the neck.
Does no-fault insurance cover this?
New York no-fault generally covers medically necessary treatment after a car accident regardless of who caused it, but there are filing deadlines. Call (631) 321-5400 and the front desk will walk you through it.
Why do my symptoms keep getting worse?
Inflammation builds over the first few days and muscles tighten protectively around the injury. Worsening in the first week is common — it is a reason to get examined, not a reason to keep waiting.
