My doctors think I have this but so far CAT scans do not show any tumors and so they have tell me there is not much they can do for me. I have gained about 40 pounds in the last year and do not feel very good about myself. I feel constant fatigue and muscel pain. It is harder and harder to go to work each day. It seems as if I have to convince my doctors there is something wrong with me. I don't know what to do. Can anyone out there help?
