Whiplash is a neck injury caused by a fast, forceful back‒and‒forth motion, most commonly during a rear‒end collision. That sudden movement can irritate muscles, ligaments, joints, and sometimes discs, which is why symptoms can show up right away or develop over the next day or two.
Because whiplash is not always “just soreness,” a focused evaluation matters. The goal is to understand what tissues seem involved, how your movement is affected, and what kind of support is most likely to help you get back to normal routines.
