There are a number of treatment options available for joint pain, and the preferred treatment will depend on the severity of your injury. The following are examples of some of the most common treatments for joint pain after a car accident:nBracing: Your doctor may recommend that you wear a brace in conjunction with rest, to help with the healing process. In addition to providing stability, a brace will help decrease movement in the joint. Your doctor will provide instruction on how to wear the brace, and how often. For example, some braces should be worn only at night, and some should be worn during the day when you are moving around more. Others should be worn at all times if the injury is more severe.nJoint injections: Most joint pain is caused by inflammation. A common treatment for this type of pain is a cortisone shot injected directly into the affected joint. In addition to reducing the inflammation and pain, this will help increase mobility. Although you may experience some pain and discomfort at the injection site during the first 24 to 48 hours, you should experience pain relief shortly after that and the pain relief should last for several months. Some joint pain is nerve based, in which case your doctor may recommend a nerve block, which is injected into the nerve in the spine that aligns with the joint pain.
