What miracle giver Mark is! I’d been to the orthopedic surgeon with a bad left knee. I could walk without a limp most times. Missing half the cartridge and full of arthritis, I was in a lot of pain as well. I tried everything the Dr asked to do; physical therapy, shots to lubricate the joints, more shots to help with the pain and have more flexibility. Nothing helped and I was on my way to a full knee replacement. Then I met Mark, and he worked on that knee and over time it got better. Now I ever go out dancing, awesome! Thanks Mark, your my secret angel.
