RSD and CRPS are the same thing! CRPS is the newest name for RSD. I really wish that doctors would come up with just ONE name for RSD/CRPS so that it doesn't confuse people even more!!!

Unfortunately, RSD can spread at any time. Some people go years without it spreading and then it suddenly will and others can go forever without it spreading. Everyone with RSD is different and no two people will react the same. Personally, my RSD spread within 4 months from my left leg to my right arm and then spread to my other arm at the beginning of this year after an injury.

I wish you the very best of luck with your block and hope you get the pain relief you need and deserve!! I didn't respond well to the blocks but some people believe that they can put any spreading to a halt so hopefully that will be the case for you!!

Take care and please keep us posted! You will be in my thoughts and prayers on Monday!
