Planter fascitis is a painful condition affecting the bottoms of the feet. It involves inflammation and tightness of the planter fascia, which is a tough layer of connective tissue on the bottoms of the feet. Trigger points in the calf and foot muscles are a leading cause of planter fascitis. These points not only cause the muscle to become tight which in turn causes the fascia to be tight, but the trigger point pain referral patterns of these muscle will cause pain to be felt in the bottoms of the feet and heal. These causes are often overlooked leading to ineffective treatment and prolonged suffering.
Myofascial pain syndrome is caused by a stimulus, such as muscle tightness, that sets off trigger points in your muscles. Factors that may increase your risk of muscle
trigger points include:
- Muscle injury. An acute muscle injury or continual muscle stress may lead to the development of trigger points. For example, a spot within or near a strained muscle may become a trigger point. Repetitive motions and poor posture also may increase your risk.
- Stress and anxiety. People who frequently experience stress and anxiety may be more likely to develop trigger points in their muscles. One theory holds that these people may be more likely to clench their muscles, a form of repeated strain that leaves muscles susceptible to trigger point
Myofascial pain syndrome is a chronic pain disorder. In this condition, pressure on sensitive points in your muscles (trigger points) causes pain in the muscle and sometimes in seemingly unrelated parts of your body. This is called referred pain.
This syndrome typically occurs after a muscle has been contracted repetitively. This can be caused by repetitive motions used in jobs or hobbies or by stress-related muscle tension.
The temporalis muscle is located on the sides of the skull at the temple. This muscle assists in jaw movements for chewing and talking etc. This muscle can become overworked from excessive clenching of the jaw and grinding of the teeth from stress. Poor neck posture can also stress the muscles of the jaw. When this happens trigger points can form. These points can refer pain into the temple, skull, and face. These trigger points can also cause tooth sensitivity and pain.
The lateral pterygoid muscle is involved in movement of the jaw. It can become become strained from chronic clenching of the jaw and grinding of the teeth. When this happened trigger points can form. This leads not only to pain and refered pain, but also dysfunctional joint mechanics. This muscle is a major player in TMJ dysfunction syndrome.
The multifidus muscle is a long muscle that travels the length of the spine. It has different actions on different parts of the spine. It extends and laterally flexes the cervical and lumbar spine, and rotates the thoracic spine. Trigger points in this muscle are common due to poor posture and bad movement mechanics. Trigger points in the lumbar area area are a common cause of low back pain. These lower points can also refer into the abdomen. Points that form in the cervical region will refer pain down the neck into the shoulder blade area.
The rectus femoris muscle is one of your quad muscles. It acts primarily to extend the knee but it also helps to flex the hip. This muscle is often overloaded from athletic activity, but it also can become chronically shortened from prolonged sitting. Trigger points will refer pain deep into the knee producing a deep ache felt into the joint.
