I was introduced to this compounded cream by a sports medicine doctor. I had busted my knee cap and torn ligaments. I've never had anything like this that absolutely works with pain and swelling. Many doctors are aware of the benefits this provides to help with the pain and swelling. I'm a firm believer of this works. I've used it on and off now for 17 years with no side effects. Do your self a favor and discuss this with your doctor.
