Thanks for all your comments and advice. Catra, sounds your on the right track, keep it up!

Its not that I dont trust my doctor, quite the opposite in fact. She is the head of the pain department in Malta and deals with loads of patients with sever pain. She did not say she is going to cure me with this PRF, just that she aims to hopefully lessen my pain or even take it away for a few week or more so i can do my rehab and then redo it again if it helps. She said she will also do the sympathetic nerve block but she persistantly wants to do this for me first as she uses it often with good resuts.
