This non-invasive form of therapy is FDA and TGA-approved, meaning it is considered safe for most people. There are some circumstances in which shockwave therapy is not recommended, such as patients who are under the age of 18, have a pacemaker, are undertaking anticoagulant therapy, have had a recent cortisone injection, or are pregnant. Shockwave therapy is not suitable for some people with medical conditions such as nerve disorders, active infections, open wounds at the affected site, and malignant tumours.
