Carolinarose, just remember results are sometimes realized later. I always flared up for a month after most of my procedures. I don't know why they just didn't give you a lumbar sympathetic nerve block. Spread to the other leg is common. Maybe they just wanted to do a diagnostic. Do you still have that red skin stuff and swelling in your right leg? Sometimes they like to see if you have warming of the limb with a block or change in appearance or see if the pain is sympathetically driven. Hope your doctor knows what they are doing and the side effects are temporary and results end up therapeutic. Sometimes blocks have to be repeated 2 or three times to hold a while.
