Prolotherapy is great for chronic pain caused by injuries that never healed properly. It hasn't hit the mainstream of medicine but it's very safe and it really works. Dr. Hurwitz taught me some of the prolotherapy techniques (after he successfully treated me for back and arm problems) and I used them in my medical practice in Miami with excellent results in patients with chronic back and shoulder pain as well as patients with headaches and knee arthritis among other disorders. Dr. Hurwitz is very knowledgeable, ethical and skilled. I know him well and highly recommend him.
