This is one of the few CFS/ME symptom charts that details one of the symptoms I have most often: feeling poisoned (and fluey, & nauseous), etc. I have all these symptoms regularly, except for the light/noise intolerance, which I feel quite lucky to say I rarely have.
Fibromyalgia is a chronic pain disorder. It's unpredictable. Symptoms come and go, and no cure exists. Despite the large number of us who live with it, the average person knows very little about fibro.
