I was diagnosed with fibro a few years ago. I'm worried sick. I've had the most horrible headache since the weekend. My neck and low back feel like they are on fire. Sunday, I could barely get out of bed to do a short walk. Monday I had the worst sweat/workout I've ever had. I Walked around the neighborhood yesterday. Today still dragging, got some good exercise. I'm having a very difficult time going up stairs. I reach the top, and have to sit. I'm out of breath. Wiped out. I'm off all meds. This can't be happening.
