Before I had the stem cells, it was very difficult to go up and down the stairs without hauling myself up with the help of the bannister. I have come a long way since then.I've felt that the injections of stem cells gave me immediate relief in pain, and mobility was greatly improved. Improvement had subsequent surges for the following 8 weeks. Now I have to remind myself of how bad I was. I can now enjoy walking up and down hills and hiking with my dogs, and in the mornings I wake up and move without pain. Dr. Evans and his staff have been excellent, professional, and kind. The procedure was fairly easy and it never stopped me from talking during it! I may not be 100%, but I will take the 80% in keeping my 70 year old self quite active without surgery.
