Regenerative medical therapies?

If you specifically mean regenerative therapy for neuropathy, I think there is some research going on but I haven't seen any treatment being offered for patients. Here's a couple of research articles I've seen.

High pressure sales is a red flag warning to me. If it's a smaller clinic and not a major hospital I would also be worried about clean rooms for the processes involved but then I'm a born skeptic and have no medical expertise.

There are also several discussions here on Connect about stem cell therapy. Here's a search of Connect that lists the different discussions - https://connect.mayoclinic.org/search/discussions/

I am desperate for relief from gluteal tendinopathy pain. I found a rehab doctor online who does regenerative medicine. In my case I was interested in platelet rich plasma injections which are not covered by insurance but Mayo and other prominent clinics say they are "promising" for this condition. I saw this guy at a seedy clinic off an alley in a shabby area. He wanted $3000 per injection. I passed on them. I have now been referred by my physical therapist to a legitimate sports medicine clinic where they do the injections for $1050. I have an appointment to discuss this. I may not have them but I feel much better about the provider.
