I have been diagnosed with fibromyalgia for 7 years.But I think I have probably had it for a very long time. My pain is transitory, but is mostly in my legs. The fibro is aggravated with the "pink" artifical sweetener, causing all the connective tissue in my neck and arms to hurt and ache. So of course I don't use it. (grin) I take a anti-inflammatory and muscle relaxant at night. Cold weather is starting to really bother me especially since I have Raynauld's Phenomena (circulation shuts off to fingertips ...you can actually cut yourself and not know it until the circulation returns) and it is extremely irritating and uncomfortable. It can last a few minutes or longer. They hurt when they get the blood flow back, also.
