Welcome to the forum. It sounds like you got to see all the dr's. in a very short time. I am glad to hear your IM gave you medications in the end, including something for your stomach.

For some reason, these dr.'s don't seem to think that all these medications tear your stomach up.

I have had lots of blocks. They give you a little anesthisia, but your awake, give you a needle in the back. If it is rsd your foot and leg may immediately to a few minutes, feel and turn bright red.

I have found I got my best results when they did them one week apart. Good luck and feel free to post.
