Smile, do you want to share your symptoms that make you wonder lately if you have FM? Please tell your researchers my experience that Tylenol does nothing, because I think that's important too. I thought the drug of choice for FM pain was NSAIDS or ibuprophen (sp.). I think it's a coincidence that the increase in diagnosis came along with an increase of Tylenol as an aid. But, I am no doctor or researcher!
