Trigger point dry needling can be used for a variety of musculoskeletal problems. Muscles are thought to be a primary contributing factor to the symptoms. Such conditions include, but are not limited to neck, back, and shoulder pain, arm pain (tennis elbow, carpal tunnel, golfer’s elbow), headache to include migraines and tension-type headaches, jaw pain, buttock pain and leg pain (sciatica, hamstring strains, calf tightness/spasms). The treatment of muscles has the greatest effect on reducing the pain mechanisms in the nervous system.
