You got the answer exactly. When a doctor doesn't know what's wrong with you the easiest thing for him/her to say is Fibromyalgia because so many symptoms are blamed on Fibromyalgia. Fibromyalgia causes real physical pain. When muscles tighten on a nerve the nerve sends a message to the brain that says "pain" and the brain sends a message back to the nerve so that the nerve can feel the pain. If you put the brain to sleep and make it unconscious, you extinguish the pain because without the brain functioning and alert the human body cannot feel pain. If a person is put under anesthesia he/she feels no pain. With Fibromyalgia a muscle tightens on a nerve, the nerve sends a message to the brain to feel the pain and the brain's response is to tighten that muscle which causes more pain. Now I don't know why the answer that I found works but it works and totally gets rid of the pain from Fibromyalgia amazingly fast. The only thing is that no one believes that it works but I have no doubt, that it works and it works unbelievably well. If you seriously want to know what it is, then ask me but ask intelligently.

It seams to me you have all yhe tests and at yhe end they don't know do let's call it fibromyalgia.i have the tiredness the pains but i know if i had this like you guys no way i would be able to work so I'm starting to think is it my age is it that i have worn my body out over yhe years i snd doctor has no answer i wish i had the answer to all the questions

My CFS was caused by sleep apnea. I was sleeping 12 to 14 hours nightly with a 2 hour nap. After testing I got a CPAP machine and now usually sleep 6 to 7 hours usually with no nap.
