I have mild shoulder osteoarthritis it’s not really painful but a lot of discomfort. I went to an Orthopedist and he suggested shoulder replacement surgery. I decided to get a second opinion and the second doc said I didn’t need my shoulder replaced. The second Orthopedist said the current data does not indicate Platelet Rich Plasma (PRP) helps osteoarthritis. Does anyone have any experience with PRP injections or stem cell injections?
