Here is something from National Spine and Pain Centers ...;.
Prolotherapy is an innovative technique that relieves pain by directly impacting the underlying condition causing that pain. In contrast to many medical treatments that may provide only temporary benefits, this safe, proven treatment offers lasting relief. Many conditions respond well to prolotherapy, such as facet syndrome (back and neck arthritis), whiplash, joint sprains, degenerative disc disease, osteoarthritis, tennis elbow, sprains, chronic tendonitis, and more.
Prolotherapy promotes long-term, often permanent pain relief by stimulating the body’s ability to repair itself. A solution of concentrated dextrose and local anesthetic (steroids are not used) is injected into the affected ligaments, tendons, or joint capsules. This solution acts not as a nutrient, but by stimulating the body’s natural ability to repair these tissues, encouraging growth of new ligament or tendon fibers.
Multiple treatments encourage additional tissue growth to restore and strengthen the affected area. An individual plan is devised with prolotherapy treatments scheduled every two to six weeks until the healing is complete, and you can return to normal activities without pain.
