My fibromyalgia symptoms began two weeks after I received the MMR vaccine. It started off as a burning sensation and subjective weakness in my arms, and over the last few years, this burning sensation is felt throughout my body, and I also have subjective weakness in my legs now too. I just feel like I always have the flu. I feel like I am 100 years old, and I am only in my 20's. My education was disrupted, and every aspect of my life is affected. My doctor who gave this vaccine to me, told me it was harmless. Look at the product monograph of the MMR (it's located on Merck's website, and you can request the MMR product monograph from any year, as the vaccine contents are modified every few years), and it doesn't look so harmless to me. And now they added bovine serum to it, and it is contaminated with nanobacteria. I wish the public were more aware of the dangers of vaccinations. Nothing is risk free!!! I too was naive, like the public is, before I was injured by a vaccination!!!
