PRP on back & shoulder stem cell treatment - no improvements

I went to Dr Wardwell for 2 different sports injuries. I unfortunately cannot recommend his work. Here are my reasons. His primary work is cosmetic surgery and not really sports injuries. He will attempt without fail to try the "latest and greatest" in my case it was stem cell treatment for a tendon in my shoulder. This I was told by 2 other doctors was not the right thing for my shoulder and there was no improvement at all and it lead to surgery by another doctor. I had arthritis and it was misdiagnosed. Only to be sent a bill (after settling everything) 3 months later for the ultrasound part of it! $500.
I also did (don't ask why I went back) PRP Plasma rich ptelete therapy on my back which also had little to no improvement. Please don't let the newest greatest thing that this doctor toutes to you blind you from perhaps the fact it isn't what you need. It sounds amazing at the time but we all love medical science and it can sometimes be a distraction from the fact that it isn't the righ thing.
