Activation of trigger points may be caused by a number of factors, including acute or chronic muscle overload, activation by other trigger points (key/satellite, primary/secondary), disease, psychological distress (via systemic inflammation), homeostatic imbalances, direct trauma to the region, collision trauma (such as a car crash which stresses many muscles and causes instant trigger points) radiculopathy, infections and health issues such as smoking.
the pectoralis major is the main muscle of the chest. It is a powerful adductor of the arm. This muscle often is tight and shortened from poor shoulder posture. Trigger points in this muscle will cause pain to refer into the chest, shoulder, and down the arm. Trigger points in the left pec can mimic heart attack and angina symptoms.
The serratus anterior muscle is responsible for scapular and rib movement and stability. This muscle can become overloaded from poor posture of the shoulders, as well as heavy breathing from exertion. Trigger points in this muscle will cause pain to be felt under the armpit into the shoulder blade area, and down the arm into the fingers.
trigger points are one of the most common sources of pain in the body. Once a trigger point has formed it won’t release on its own. Trigger point massage is one of the most effective way to release a point. It involves using a deep focused pressure applied directly to the knot. This frees the contracted tissue and stimulates healing.
Myofascial trigger points form in a muscle due to overload stress. A portion of muscle fibers lock up into a knot. Once formed these points will irritate sensory nerves that are in proximity to the knot. When this happens,
trigger points have the capacity to refer pain along specific distributions or patterns that are well mapped out. sometimes pain may be felt at a great distance away from the actual point itself.
Trigger points are knots of contracted muscle or connective tissue that form as a result of overload stress. Once formed these points will produce pain, refered pain, weakness, and stiffness. Trigger points can also mimic other conditions such as Carple tunnel syndrome and sciatica. Trigger points will on go away on their own, they must be manually released.
The trapezius muscle is a large diamond shaped muscle located in your back. This muscle is often overloaded due to poor sitting posture or excessive exercise. When this occurs trigger points will form. These points can cause back, neck, and shoulder pain. Trigger points in the upper traps are a leading cause of headache.
