These waves stimulate the body’s natural healing response, increasing blood flow and stimulating the production of new tissue. Shock wave therapy is typically performed as an outpatient procedure and does not require anesthesia. Treatment sessions may last from 15 minutes to an hour, depending on the condition being treated. While shock wave therapy is generally considered safe, there may be some side effects, such as mild discomfort, bruising, or swelling around the treatment area. If you are considering shock wave therapy, it is important to consult with your doctor or a qualified healthcare professional to determine if it is the right treatment for you.
