This is my first time posting on one of these boards. I have recently battled a 4 day severe reaction to H2O2 I.V. therapy. I have Fibromyalgia and CFS. This is what my Doc. and I were treating with the therapy. I know there are posts on here about this therapy, but I couldn't find anyone who had a bad reaction to it. I had done the first treatment a few days before Christmas and on the 3rd day I ended up flaring pretty hard and it lasted a couple days. Then i recouped. This second try at the H2O2 therapy was about a week ago. And on the early part of the third day my pain began to rise exponentially with the hours until that evening I was maxed out. I ended up in the worst fibro pain of my life. I felt like I was burning from the inside out.This persisted for over 3 days at which I got only a COMBINED total of 6 hrs. of sleep in those 3 days, and that was only when my body couldn't stand up anymore. Sorry for the gross factor, but I also ended up "releasing my stomach contents" all day Saturday from the pain and lack of sleep. I could feel my brain slipping because of it all. I finally ended up at the emergency room Saturday night (I have never had to go to the emergency room for my fibro). When I got there my blood pressure was really high. They had to give me this drug called.... not sure of spelling-Dilauded?, had never taken it before & they said it was 10x stronger than Morphine. They had to give me 3 shots of that plus a drug called Adivan? and an anti-nausea. This was all soooo embarrassing for me. I do not like "pain killer seeking" and I was crying so much in public from it all, not to mention the big white salad bowl I had to carry with me for the tummy problems; of which will no longer be used for salad.... hehehe. I finally passed out at the hospital and slept almost the entire day of sunday an a large part of today (Monday). I am sorry this is soooo long. But I really need to know if anyone else has experienced this. My doc says I woke up a "Very angry, monster that put my immune system in overdrive too hard and too fast." This might be true because at the emergency room my white blood cell count was tested and it was elevated.... go figure? I do have to say that I have the BEST protective and caring husband in the world who was my only rock through it all and brought me back my sanity and control.
