Trigger points in the rectus femoris muscle.

The Rectus Femoris muscle is one of the muscles that makes up the quadriceps group. It works to extend the knee and flex the hip. Trigger points that form in the Rectus Femoris are an often overlooked source of knee pain. The pain is usually described as a achy pain felt deep in the joint.

Trigger points in the diaphragm

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.

Planter fascitis and trigger points

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.

Trigger points in the multifidus muscle.

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.
