Prolotherapy is also called RIT (rejuvenation injection therapy) and is used to treat pain by the injection of biological natural substances and local anesthetics into ligaments, tendons, and joint spaces. The injections induce the tissues to release various growth factors to stimulate and promote tissue healing and strengthening. There are no steroids used. Even though Prolotherapy has been used for over 75 years in Europe and the USA, insurance companies will not cover the cost of the procedure.
