@mrmacabre I agree that it is expensive depending on where you go and there are no guaranties. However, there are no guaranties with anything, injections, acupuncture, ablation, surgery, etc. I had some relief briefly with placental tissue matrix injections, which is similar to stem cells, here in the US, and they have better products outside the US. To me, it is worth investigating given the amount of pain I live in.
