Week one is the acute phase. Pain and stiffness usually peak between 24 and 72 hours after the crash, not at the scene. The right care in this window is conservative: rest, ice or heat as tolerated, and an early evaluation with a chiropractor or pain-management physician. Imaging is ordered if there's neurological involvement or red-flag findings; otherwise, plain X-rays are usually enough to rule out fracture.
Weeks two and three are about restoring range of motion. Physical therapy or chiropractic adjustments two to three times per week is typical. Most patients see a measurable improvement in cervical rotation by the end of week three. Headaches and sleep disruption often persist into this window — that's normal, but should be tracked.
Weeks four through six are about strength and return to normal activity. By week six, the majority of straightforward whiplash patients are at 80–100% of pre-injury function. Persistent radiating pain, numbness, or weakness past this point usually triggers a referral to neurology or spine surgery for re-evaluation — not because something has gone wrong, but because the diagnosis needs to broaden.
Warning signs at any point: weakness in an arm or hand, loss of bladder or bowel control, severe headache with vision changes, or pain that wakes you from sleep. Any of these means same-day evaluation, not waiting for the next scheduled visit.
