... my orthopedic, my rheumatologist and even my son's rheumatologist say I will definitely have a major fibromyalgia flare up from the surgery. I am so scared and have been holding off the surgery for a year now. My pain doctor has been doing minor procedures to try and help keep the pain bearable. At this point things aren't helping as well and I know I need to have the surgery eventually. If you have gone through surgery and had a flare up from it, how bad was it? Did you regret having the surgery? If I know how bad it would be I can prepare for it. I think I'm scared because I don't know what to expect
