Hi,
I'm sorry to hear that the PT program didn't help you

I have only had 1 sympathetic nerve block - I had the block done the day after I was diagnosed with RSD by a Pain Management Doctor. My Doctor injected directly into my left leg which has RSD and I developed complications from the block - it was only after I had the nerve block that we found out that you SHOULDN'T have a nerve block directly into the site that has RSD. I hope I didn't scare you, I just don't want you to have a block into the site that has RSD like I did and then suffer from complications.
I have heard many people say that nerve blocks are really good and effective if the RSD is caught early enough - I was told that the best chance of the nerve block working is if you are diagnosed with RSD within 3 months. Most nerve blocks are done by Pain Management Doctors usually in their office, although because of my age I was given the nerve block whilst under general anasthetic.
I wish you the very best of luck!!
Alison
