All muscles. abdominal obliques. abductor digiti minimi (foot) abductor digiti minimi (hand) abductor hallucis. adductor longus and brevis. adductor magnus. adductor pollicis. anconeus. A trigger point (trp) is a hyperirritable spot, a palpable nodule in the taut bands of the skeletal muscles' fascia. direct compression or muscle contraction can elicit jump sign, local tenderness, local twitch response and referred pain which usually responds with a pain pattern distant from the spot.
Trigger point injection is indicated for patients who have symptomatic active trigger points that produce a twitch response to pressure and create a pattern of referred pain. Masseter trigger point diagram. pain into the upper and lower molars from the masseter muscle can be the source of ongoing tooth pain which the patient and dentist find difficult to treat. referred pain and tenderness from masseter trps may cause tooth hypersensitivity to any or all stimuli: occlusal pressure, percussion, heat and cold. The x's represent the trigger points. the red dotted area is the referred pain caused by the trigger point and the solid red means more people experienced pain in that area. the dark green color areas represent the muscles of the human body. This muscle can contain three trigger points, arranged in a triangular pattern within the belly of the muscle. in my experience, the lower trigger point is the most common and most active in shoulder complaints. referred pain from these trigger points is experienced deep in the front of the shoulder joint and along the upper arm.

Trigger points are classified as being active or latent, depending on their clinical characteris tics.5 an active trigger point causes pain at rest. it is tender to palpation with a referred pain pat. The pain is usually felt at the site of the trigger point and can also radiate to other areas. this referred pain can sometimes follow specific patterns. latent trigger points: these are dormant and don’t cause spontaneous pain, but they can restrict movement and cause muscle weakness. when pressed or stretched, they can become painful.
