Often trigger points develop because of referred pain, or pain from another source that has manifested itself in a trigger point. Trigger points rarely refer pain to other areas. Trigger Point Therapy seeks first to identify trigger points, and then apply steady, appropriate pressure to the point to "release" it. This is usually followed by a massage to the surrounding area to help treat the cause of the trigger point. Clients are encouraged to drink a lot of water following a trigger point therapy session to flush out any toxins released when the trigger point is released.
