The temporalis muscle is located in the temple area of the skull. It originates on the temporal lines on the parietal bone of the skull, and inserts on the coronoid process of the mandible. It’s main action is to close the jaw. The posterior and middle fibres bilaterally retrude the mandible. Acting individually, this muscle will deviate the mandible to the same side. Trigger points in this muscle refer into the teeth causing hypersensitivity, and into and above the eye and temple, causing headaches.

Do you wake up with numb fingers?
The term “thoracic outlet” describes an area at the base of your neck, just above your collarbone. Some important nerves and vessels pass through this outlet on their way into your arm. Compression of these tissues causes a condition called “thoracic outlet syndrome” which results in pain, numbness or tingling in your arm.
Several different factors can cause Thoracic Outlet Syndrome,
commonly referred to as TOS. Sometimes TOS is caused from tightness in the muscles of your neck and chest, other times the space between your first rib and collarbone is too small. People who have an extra rib (cervical rib) and people who have recently suffered a neck injury may have a greater chance of having this problem.
The condition is aggravated by poor posture and by occupations that promote “slouching,” i.e., computer users, assembly line workers, supermarket checkers and students. Swimmers, volleyball players, tennis players, baseball pitchers and occupations requiring prolonged overhead activity. i.e., electricians and painters are also prime candidates for TOS.
Symptoms of TOS include arm pain, numbness, tingling and possible weakness. Neck, arm and hand pain may begin slowly and are often aggravated by elevation of the arms or excessive head movement. Loss of grip strength is possible.
Conservative treatment, like the kind we provide, has been shown to be effective at treating TOS. Through our careful exam we have identified your specific sites of compression and will use some of the following treatment to help:
You should avoid carrying heavy loads, especially on your shoulder i.e., carpet rolls. Briefcases, laptop cases or heavy shoulder bags should be lightened. Bra straps may need additional padding or consideration of replacement with a sports bra.
Trigger points in the lateral pterygoid
The lateral pterygoid muscle plays an important role in prober jaw function. It originates on the greater wing of the sphenoid bone and the lateral pterygoid plate, and inserts on the condyloid process of the mandible. It’s action is to pull the head of the mandibular condyle out of the mandibular fossa while opening the jaw. When trigger points develop they refer pain into the temporal mandibular joint and maxillary sinus. This referral is commonly mistaken for TM arthritis. In addition to the referral pain, trigger points in this muscle can also effect proper movement of the jaw.
Trigger points in the serratus anterior
The serratus anterior muscle is located along the sides of the ribs. It originates on the outer surface of the upper 8-9ribs, and inserts on the medial border of the scapula. This muscle acts on the scapula in several different ways. First it rotates the scapula to turn the glenoid fossa upward. It also protracted and elevates the scapula. And lastly it helps to prevent wining. This muscle is often shortened from prolonged sitting and work on a computer. Active trigger points in this muscle refer pain locally around the trigger point with spillover down the inside of the arm. Pain can also radiate into the inferior angle of the scapula. 
Trigger points in the iliopsoas muscle
This muscle originates on the bodies and disks of T12-L5 and the inner ilium. It inserts on the lesser trochanter of the femur. The psoas flexes the hip when the spine is fixed. When the leg is fixed it extends the lumbar spine increasing lumbar lordosis. This Muscle is often chronically shortened due to inactivity and sitting posture. When trigger points are present they will refer pain primarily to the lower lumbar area and the sacrum as well as into the anterior thigh. Trigger points in the iliopsoas muscle can mimic appendicitis.
Trigger points in the piriformis muscle
The piriformis muscle is a small muscle deep to glute max and lies over top of the sciatic nerve. It originates on the anterior sacrum, and inserts on the greater trochanter of the femur. It’s main action is to laterally rotate the femur. When trigger points developed in this muscle they will refer pain into the sacro-iliac region, across the posterior hip and down the leg. This muscle can also be a cause of sciatic nerve irritation if it gets tight, causing “sciatica” symptoms. 
Piriformis Syndrome; a real bummer.
Piriformis syndrome results from compression of the sciatic nerve as it passes underneath a muscle in your buttock called the piriformis. Your piriformis muscle attaches from the lowest part of your spine (sacrum) and travels across to your hip. The muscle helps to rotate your leg outward when it contracts. In most people, the sciatic nerve travels deep to the piriformis muscle.
When your piriformis muscle is irritated or goes into spasm, it may cause a painful compression of your sciatic nerve. Approximately ¼ of the population is more likely to suffer from piriformis syndrome because their sciatic nerve passes through the muscle.
Piriformis syndrome may begin suddenly as a result of an injury or may develop slowly from repeated irritation. Common causes include: a fall onto the buttocks, catching oneself from a “near fall,” strains, long distance walking, stair climbing or sitting on the edge of a hard surface or wallet. In many cases, a specific triggering event cannot be pinpointed. The condition is most common in 40-60 year olds and affects women more often than men.
Symptoms of piriformis syndrome include pain, numbness or tingling that begins in your buttock and radiates along the course of your sciatic nerve toward your foot. Symptoms often increase when you are sitting or standing in one position for longer than 15-20 minutes. Changing positions may help. You may notice that your symptoms increase when you walk, run, climb stairs, ride in a car, sit cross-legged or get up from a chair.
Sciatic arising from piriformis syndrome is one of the most treatable varieties and generally is relieved by the type of treatment provided in this office. You may need to temporarily limit activities that aggravate the piriformis muscle, including hill and stair climbing, walking on uneven surfaces, intense downhill running or twisting and throwing objects backwards, i.e., firewood. Be sure to avoid sitting on one foot and take frequent breaks from prolonged standing, sitting and car rides. You may find relief by applying an ice pack to your buttock for 15-20 minutes at a time, several times throughout the day.
Trigger points in the gluteus minimus
The gluteus minimus is a small but important muscle that lies deep to the gluteus medius. It originates on the gluteal surface of the ilium, and attaches on the greater trochanter of the femur. It’s main actions are to abduct and medically rotate the hip. Trigger points in this muscle refer pain into the buttock and down the lateral and posterior leg, mimicking sciatica. This muscle should be the first to be examined if a straight leg test turns out negative. 
Trigger points in the gluteus medius muscle
The gluteus medius muscle plays an important role in hip and pelvic stability. It originates on the gluteal surface of the ilium, deep to the gluteus Maximus. It inserts on the greater trochanter of the femur. It’s main actions are to abduct the hip and to assist in internal rotation of the hip. It also maintains pelvic stability during walking and running. Trigger points in this muscle will refer pain into the sacrum, the iliac crest, and down the lateral hip and into the thigh. This muscle is often a cause of lower pack pain.
Trigger points in the gluteus Maximus
The gluteus Maximus is the buttock muscle. It originates on the gluteal surface of the ilium, lumbar fascia, sacrum and sacrotuberous ligament. It inserts on the gluteal tuberosity of the femur and the iliotibial tract. Extension and lateral rotation of the hip are it’s main actions. This muscle is heavily involved in activities like ice skating and is a common area to develops trigger points. When trigger points do develop they can refer pain in a crescent pattern from the gluteal fold to the sacrum. Trigger points can also refer pain deep into the buttock itself making it feel like other deeper muscles are involved. These symptoms can sometimes be mistaken for s.i. Joint problems.
