Dry needling does not interfere with the bodys natural process; instead it improves the bodys internal balance and normalizes body functions while promoting self-healing. The lesions stimulate physiological processes, which can involve endorphin release, anti-inflammatory responses, hormonal balancing, and regeneration of fresh tissue. In treating pain, dry needling can loosen adhesions, scar tissue and relax contractures, as well as be helpful in non-pain conditions such as sinusitis and headaches, and its relaxing benefit may even help insomnia and anxiety.
