hi ruby,,,,,,,I hope and pray that you dont have RSD,,listen to the advice to the upper posts and you might want to see a pain management Dr to get an RSD dx.....dont put it off,,if your in the early stages ,its inperaative that you get all the vastly need care that you can,,,,Im hopeing you can get blocks injections to slow it down,,,as Ada noted ,a good anesthologist and pain managementdr;s are a very good way to start to get the Dx that you need,and the proper care,,,,Time is an issue and is a valuable thing not to waste when dealing with RSD,best wishes,,,,I do hope that its anything else but rsd,,,,
