I'm a bit desperate, so I'm asking what seems like a very silly question. I've always read that fibromyalgia's primary symptom is chronic pain, but I'm still desparately searching for a diagnosis for my strange problems. I have sleep apnea, which is being treated. I also have IBS and GERD. While I'm overweight, I also try to exercise 4-6 times a week. I have very dry eyes and skin, but came up negative for Sjogren's Syndrome. My major problem these days seems to be the onset of chills without fever. I just had a particularly bizarre instance of this, in which I found it impossible to get warm for almost an hour. My fingers were stiff and didn't work properly, my teeth were chattering, and I had a dull pain in both arms and legs. Now that the bout is over, I feel very weak and my muscles are extremely fatigued. My other problem is that I feel muscle weakness in my legs almost every other day when I prepare to exercise. They feel shaky and as if they don't want to support me. This has become very alarming to me, as I need to keep exercising to avoid health problems. I realize that these symptoms are probably not fibromyalgia, since I have no bad chronic pain. But maybe someone on the board who has researched their condition might have some idea what's going on? Best wishes, Sue K.
