Last night I had the worst pain I’ve ever had all over my body. It started in my knees and elbows, then my hands and feet, the back of my head, my shoulders and chest. It was excruciating. I looked up fibromyalgia and it sounds exactly what happened to me. My question is does the onset of fibro come on gradually through the day? It seems to have settled down at the moment but the pain was beyond words, I felt like I needed to call an ambulance. I’m still thinking about going to the hospital but they will probably just refer me to an arthritis doctor. Has anyone out there ever experienced this quick onset of full body pain?
