take a close look at your environment, at work, at home...has something changed in the past that may have made these symptoms creep up on you? I dont want to make you paranoid, but I was exposed to mold and couldnt figure it out for a long time because I have allergy problems anyway. I think if it was that, you would have a sinus infection..soreness in the joints, loss of appetite, dizziness, fatigue. PLEASE talk to a doctor about this!!!!!!! And write everything down that you want to talk about before you go..be prepared..help the doctor help you!! express a concern if they just prescribe an antibiotic, and try to send you out the door.. antibiotics can harm benefitial micro-organisms in the body, and you may need to replace them.
