I was diagnosed with Fibromyalgia 4 years ago and for the last year or 2 have been leading a completely "normal" life. Sleeping pretty well, very little to no muscle pain , very little anxiety and my ability to handle stress was good. I finally felt good enough to pay attention to the dental work I needed and had put off for so long. My dentist convinced me to get a crown on one of my teeth.... I want add that all my healing has been due to alot of hard work on my part-- exericise, diet changes, going completely chemical free etc and alternative therapies. I don't do drugs. I know I am sensitive as I believe most people with CFS and Fibro are. Anyway-- since I got my permanent crown 2 days ago---- which was porcelain on metal- I haven't been able to sleep, been twitching when I start to fall asleep, feel the anxiety I felt 4 years ago when I couldn't sleep at all........ I'm scared that I have really set of something in action....could be I should have never had the dental work done, or gone with an all porcelain instead of metal/porc. crown one. I don't know...... has anyone experienced a major flare up from dental work? crowns etc? I had done research on a really good alternative dentist 4 years ago. who treats many chemically sensitive individuals out in California. Dr. Richard Hansen in Fullerton, CA. Unfortunately , I set the work aside and it didn't go bck to it feeling very confidient that I was strong and healthy now..... he actually claims he can restore cracks instead of grinding the tooth down to nothing and putting on a crown....they do biocompatiability testing et. having big regrets now on what I've done. I hope my body is just "adjusting" to the new materials and will settle down.. Please let me know if you've had any similiar experiences.
