Two weeks ago I received a prolozone injection from Dr. Hanson. I have had chronic back pain for twenty years with severe degenerative disc disease per x-ray and have seen doctors and taken nsaids. I had a recent exacerbation of back pain lasting about a month prior to the injection. Immediately After the prolozone injection my back pain was almost gone. I currently have no pain. If you have joint pain and want a treatment that actually heals the tissue I would recommend this to anyone. It is safe, pain free and inexpensive.
