Trigger points can become problematic for a number of reasons. Patients may develop trigger points because of injury to muscle tissue. Examples of muscular injury include whiplash, overuse of a muscle group, or a post viral syndrome. Trigger points may also occur because of an underlying structural problem. Spinal abnormalities such as herniated and degenerative discs, scoliosis, postural problems, osteoarthritis are examples of conditions commonly associated with trigger points.
