I am in a similar situation as you are, only I have foot issues now and going in for the knee replacement surgery in a few months.
I have gotten Cortisone shots for the fasciitis and that usually works, but not recently.
My podiatrist has suggested stem cell therapy which I am considering in a week or so.
The podiatrist said he has had good results with this stem cell therapy. It may help with the knee replacement as well, but I do not know for sure.
You might see if that is something you would find helpful.
I live in West Palm Beach Florida.
The podiatrist is Dr. Cutler in Royal Palm Beach Florida a suburb of the city I live in.
If you need any more information, I will try to get it to you.
