Agreed. Guided by an outstanding physician I have have had prolotherapy, platelet rich plasma and stem cell injections to treat various joints, ligaments and other pains. Each has a specific value ... and of course commensurate cost (only some of which is covered by Medicare). In my opinion it is worth pursuing to avoid surgery or replacements, until there is no other remedy. FWIW, I have worked with Dr. David Wang who was an instructor at Harvard Medical School and is now in private practice. Can look him up and watch helpful lectures here: https://kaplanclinic.com/author/dr-wang/ Hope this helps.
Thank you BK I will look into that.
