Although whiplash is technically considered a soft tissue injury, it is not an injury to be taken lightly. This type of injury affects your neck and the surrounding muscles of your spine. Whiplash causes severe stiffness and pain in your neck, shoulders and head. You may also experience migraines, blurred vision as well as temporary loss of mobility in your neck. Benefits of receiving physical therapy treatment can relieve the tension and allow you to recovery from the injury. This will also help strengthen your neck and shoulder muscles and prevent any future whiplash injuries.
