thanks, the first two blocks worked for 8 hrs / 5 days, so i was hoping my 3rd and 4th would go even farther... my 3rd didnt work at all...and this 4th one worked a few hours....now my pain is worse than its ever been ... i have an appointment with my pain management dr June 2nd, a neurologist next week, and i have physical therapy once a week - id do it more, but with my insurance it gets very expensive .. my primary dr knows of RSD, and has pointed me to all the other professionals that are good , he just doesnt know much to help me himself, which is understandable - ive had to fight to get all my appointments so quickly...they wanted me to wait til the end of august, when i made these appointments 2 months ago! i hope i can find a different plan of attack, now that i know my shots arent helping me
