If you have lingering pain from a tendon injury, a shock to your system may be exactly what you need. A treatment known as extracorporeal shock wave therapy (ESWT) targets damaged tendons with powerful energy waves that promote healing. Theres no anesthesia, no incisions, no stitches, and no recovery period. If youre looking for a treatment that can augment your response to whatever type of rehab youre doing to treat a tendon problem, shock wave therapy is a good way to help manage the pain and promote healing, says Susan Joy, MD, Director of Womens Sports Health at Cleveland Clinic. Its an effective non-invasive option for people with certain tendon injuries.
