I am now able to sleep on right shoulder. I have complete movement with no pain. In my right knee, I have full range of motion; I now can walk up and down stairs without pain, as well as going for a swim or squatting. In my left knee, I have complete range of motion with no stiffness. I can walk up and down stairs with very little discomfort, no pain sitting! I would tell a friend or anyone who wanted to check into cell therapy treatment to consider Dr. Darr first! Easy to get an appointment right away and his assistant shows as much concern and kindness as Dr. Darr. I have even discussed the cell therapy procedure with interested people on an airplane.
