I paid $1700 for PRP and anesthesia. I’m in the Atlanta, GA area. While I’m in worse pain than before, my pain doctor told me to not give up on the procedure yet. Hopefully it will work. As there’s not a whole lot that will help, if you can afford the PRP procedure it’s worth a try. I read it was 70% effective but it didn’t state the SI joints specifically. The steroid shots do nothing for me and the Oxycodone I was taking for years just stopped working. Apparently people get PRP injections in their scalp (for more hair growth). I read that it caused some hair loss but that the hair grew back stronger. I mention that because I noticed more hair on my brush than normal so I looked it up. While the shot was for the SI joints and not on the scalp, IMO wherever you get the shot it will go into your blood system. I hope it works for you. Please let me know your progress.
