Patty-
Welcome to this site. You will find it very helpful if you have questions or just need support. This is a good place to talk with others who understand what it is like to live with rsd/crps.
I was diagnosed in april by my podiatrist and then sent to a pain managment doctor who confermed it. I had sprained my ankel/foot in march at work. The first doc I was sent to was reaaly bad. He kept saying nothing was really wrong and it shouldn't be hurting this bad or you must have a low pain tolerance. That was when I switched docs.
You need to make sure you are dealing with a doc who understands rsd/crps. You should try to see a pain managment doc. The earlier you get treatment the betterr off you will be.
I was a little confused by your post, did they say you do have rsd or do you think it's rsd? Well' either way make sure your doc is someone you like.
Good luck,
Zim
