Whiplash after a car accident: the first 72 hours
Whiplash is the common name for a neck strain that happens when the head is thrown quickly back and forth, most often in a rear-end collision. The muscles, ligaments, and joints of the neck get stretched further than they are built to go. What surprises most people is the timing: you can walk away from a crash feeling fine and wake up stiff, sore, and headachy a day or two later.
Symptoms often arrive late
Adrenaline masks pain at the scene. Neck stiffness, headaches that start at the base of the skull, shoulder and upper-back pain, dizziness, and a foggy feeling commonly show up 24 to 72 hours after the crash. Feeling fine at the scene does not mean the neck escaped unhurt — it means the symptoms had not caught up yet.
What to do first
Get checked promptly, even if you feel okay. Tell the provider exactly what happened — the direction of the impact, your speed, whether you saw it coming, and where you feel anything at all, even mild. Keep simple notes in the days after: what hurts, when it started, and what makes it better or worse. Records made close to the date of the crash matter for insurance claims, and they help your provider track how you are recovering. If you have questions about coverage, ask your insurer about your own policy.
What helps the neck
Extended bed rest and long-term collar use usually slow recovery — gentle movement as tolerated is often better, following your provider's guidance. Ice can calm soreness in the first day or two; heat often feels better on tight muscles after that. A supportive pillow, screen breaks, and avoiding heavy lifting while the neck is irritated all help. The goal in the first days is to keep the neck moving gently, not to push through sharp pain.
Red flags — get urgent care
Seek emergency or urgent care right away for loss of consciousness, a severe or worsening headache, numbness or weakness in the arms or hands, dizziness or vision changes, or neck pain after a high-speed crash. Those signs should never wait for a routine appointment.
If you were in a wreck and your neck is telling you about it — now or a few days later — an evaluation can sort out what was strained and what kind of care makes sense. Our car accident care starts with a careful history and examination, and we document your injuries and progress along the way.
