Welcome to Neuro Talk. Glad you have been reading the posts. I have PN or RSD in left foot and ankle as well. My doctors have tried pain patches, mild pain medicaiton, and basically to leave it alone unless it gets alot worse. Mine has not spread. I agree with the other post, don't do the invasive treatment, unless your pain is such it warrents that. I was to have surgery again on the ankle, docs said No to anything that cuts or stabs including shots into the ankle at this point. Get it in writing that he would accept responsibility for the proceedure if it didn't work. I would also seek another opinion before doing that particular proceedure. I play it safe at this point. I hope what ever you decide to do, is right for you and that it works. ginnie
