If you have sustained a back or neck injury in a car accident, the most common treatment will likely be some form of physical therapy. Physical therapy can help to alleviate pain, improve mobility, and promote healing. The specific type of physical therapy that your doctor recommends will depend on the type and severity of your injury. For example, you may be prescribed exercises to strengthen your back or neck muscles, or you may be given stretches to help improve your flexibility. Your doctor may also recommend other treatments, such as medication to control pain or inflammation, or hot or cold therapy to help reduce swelling. In some cases, surgery may be necessary to treat more severe injuries.
