Hi, I m 18, a female, and I m always so tired. I eat well and exercise regularly, but I m always in pain I ve been to the ER and doctor many times and all.they do is give me.drugs and send me home I was looking at the symptoms that I have and they all seem to match up with fibromyalgia symptoms, including the fact that I have anxiety. Do you think it could be fibromyalgia?
