Done under ultrasound guidance, Trigger points are specific places on the body where muscle fibers become tight due to stress or injury. Treats muscle fibers sometimes referred to as a muscle knot (trigger points), and can usually be felt under the skin as a raised bump or nodule.
Typically these trigger points will be sensitive or tender to the touch or when pressure is placed upon them, and the tenderness or pain can even extend outward a certain distance from the trigger point. Sometimes pressure on the trigger point will elicit a muscle twitch in the related muscle fibers.
Myofascial pain syndrome is characterized by chronic pain in which compression of a person’s trigger points leads to pain in seemingly unrelated areas of the body, called referred pain. Among the forms of treatment for this disorder are massage therapy, or manual therapy, topical sprays and trigger point injections.
Trigger point injections have been shown to be one of the most effective treatments for inactivating trigger points and providing patients with pain relief.
