hi bio. i know it's hard but try to stay as calm as you can. stressing out only makes symptoms worse. maybe you are having a reaction to cortisone and the new med and that's why the pa said to stop taking it. just try to rest and see if the symptoms you are experiencing subside. i'm not a dr but know that when i have bad reactions to things that it aggravates my rsd. if that is also the case with you then that may subside too after you are off the cortisone and new med for a while. if i were you i would confirm all of this with your dr when he returns and also keep in touch with your pa too. try to stay calm and breath and rest. i know it's scary when you have other health issues on top of rsd but you are not alone and i am sending soft hugs and prayers your way. just keep telling yourself that this too shall pass. if things get worse then the er is another option but try to stay positive and calm and know that i'm here if you need to talk.
