Have you heard of TRIGGER POINTS?
Trigger points are what people commonly refer to as muscle “knots”. Trigger points are contracted muscle fibers within a muscle. When muscle fibers are contracted, they are shortened. When the muscle is shortened, it affects the muscles strength and also the range of motion of that muscle. These shortened fibers can also cause the muscle bundle to pull on its attachments which can cause pain in the joints they are attached to. Trigger points can be treated and eliminated with massage therapy as well as other soft tissue techniques like graston.
Trigger points can also cause referral pain in other areas of the body. It is possible to have trigger points in your back causing pain in your shoulder or vice versa. It is important to get your condition reviewed and examined by your chiropractor to determine what course of treatment would be best for you.
