Dry needling is a therapeutic procedure involving the insertion of thin, sterile needles into muscular trigger points, which are tight and irritable knots of muscle fibers. A healthcare provider performs the procedure to stimulate a healing response and manage pain and movement impairments. The needles are called "dry" because no medication or fluid is injected into the body. 

Muscle pain and tightness:  Dry needling can stimulate the release of endorphins, which have pain-relieving effects. It can also break up muscle knots and trigger points, reducing pain and stiffness. 

Tendinopathy:  By inserting needles into inflamed tendons, dry needling can promote healing and reduce pain. 

Myofascial pain syndrome:  This condition involves chronic pain caused by tight and tender muscle bands. Dry needling can help release these bands and improve pain management. 

Neck and back pain:  Dry needling can be used to treat pain and improve mobility in these areas. 

Headaches:  Dry needling can help relieve tension headaches and migraines. 

Sports injuries:  Dry needling can help accelerate recovery from sports injuries by reducing inflammation and improving muscle function.
