Dry needling is a treatment that healthcare providers use for pain and movement issues associated with myofascial trigger points. Trigger points are adhesions in the muscles that can contribute to pain, decreased flexibility and decreased muscle function. With this technique, a provider inserts thin needles into or near your trigger points to deactivate and desensitize them. The needles stimulate your muscles, which causes them to contract or twitch. Other dry needling benefits include boosting blood flow, diminishing inflammation, trigger healing.
