The diaphragm is the major muscle of respiration. It’s main action is to increase the volume of the thoracic cavity during inhalation. Trigger points form in this muscle due to asthma, emotional overload, disk problems, weak abdominals, hyperventilating, smoking, and poor posture. When trigger points form they can cause a wide variety of symptoms including hyperventilation syndrome, heart and lung issues, as well as a “stitch” pain when running or exercising.
Myofascial trigger points in the neck muscles are one of the most common causes of neck pain and stiffness. Poor posture and stress can cause muscles in the neck to become overworked and strained. When this happens trigger points will form. These points of contracted muscle will cause pain, referred pain (often into the head), as well as stiffness and weakness. Trigger points won’t resolve on there own, a manual release such as trigger point massage is required to treat the problem.
The levator scapulae muscle is located in your neck. It is responsible for raising your shoulder blade up to your ear, as well as side flexion of the neck. Trigger points develop in this muscle commonly due to poor posture, and stress holding patterns. Once developed these trigger points will cause a deep achy pain and stiffness in the neck.
The Brachioradialis muscle is a muscle located in your forearm. It helps to flex the elbow during semi pronation, such as when drinking a cup of coffee or holding a phone to your ear. When trigger points form in this muscle pain can be felt in the forearm, back of the elbow, and even into the hand.
One of the most common sources of headache pain is trigger points in the neck muscles. These muscles are often overloaded from poor posture such as sitting in front of a computer or looking down at you phone for long periods of time. Trigger points that form in the upper traps are the most common trigger points in the body. They refer pain up the neck, behind the ear into the temple. The suboccipital muscles refer pain deep into the skull behind the eye. Sternocleidomastoid trigger points will refer pain to the top of the head and around the orbit of the eye. Trigger points need to be manually released to be resolved.
The gluteus medius muscle is located in the hip. It is a major pelvic stabilizer during walking and running. It is also a main abductor of the hip. Trigger points in this muscle will refer pain deep into the sacrum and s.i. joints. Pain will also be refered into the buttock as well as into the low back along the belt line.
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
