Good question. Call your chiro and tell him that you are in a pain flare and need to call back to reschedule. if the doctor knows anything about rsd, then he would understand. MOST offices will NOT charge you for something like that. It isnt because we are leisurely not coming in. Thats interesting you have a SCS as well... personally for me I am too scared to see a chiro to get adjusted with the leads. Especially if you say he is not aware and paying attention before adjusting you... I know the feeling of trying to hold onto any threads of hope you have. Many of us are in your same position. I would say wait, and then sit down with your pain doctor. If he is always rushed, when he walks in say that this is really important that he takes the time for you. This needs to be addressed for treatement because of the pain. REMEMBER YOU ARE PAYING THEM, THEY WORK FOR YOU. They aren't paying you...
My heart truly goes out to you.

I wish I could do something to help. Know you are being prayed for. hang in there and let me know what they end up saying
