now that the winter is here and the roads are slippery, whiplash injuries becomes very common. Most people think of their spine and head when dealing with whiplash, but the muscles of the neck and upper back are always affected as well. Muscles in the neck will develop trigger points from the violent whipping motion of the head that occurs with this injury. Left unchecked these points will continue to produce pain, stiffness and weakness. Trigger points in the neck are one of the most common sources of headache pain. Make sure you are getting the soft tissue treated as well as the spine if you are recovering from a whiplash injury.
