I am not coordinated enough to find the pictures of your toes!! I am directionally dysfunctional.....even on the forum!!! I'll keep trying, but from your description.......it IS absolutely the RSD. Your doc should know that.

I am pretty sure that the other conditions would not show up on an MRI. I think you would need a nerve conduction test or something. I'll try to do some research and see what I can find.

I'll check to see what I can find out about the toenails too. I'm not sure what they can do about that......you just want to watch very closely to make sure they don't get infected. Let me go research for you......I'll write back in a few. Hugs!!
