Shockwave therapy is one kind of treatment that does not enter the body. Washington State Health Care Authority states that this therapy is a non-invasive treatment that specifically uses acoustic waves to promote healing; it enhances blood circulation and tissue repair, thus becoming very effective in treating a lot of different chronic pains, such as tendinitis, tennis elbow, and muscle tension. For people troubled by persistent pain or injuries that persist despite common treatments, significant relief may be achieved with this form of therapy. Scheduling a session can be a very good alternative to more intrusive options.
