For the past four days, I have had the following symptoms: extreme fatigue (awake for two hours, then need to sleep for at least four hours); dull, achy ear pain in left ear; dull, throbbing headache; loss of appetite. I have a doctor s appointment on Monday with a new physician (just moved into a new place). I ve tested positive for mononucleosis on four separate occasions (the last one several years ago) and the symptoms of the last four days are the same ones I ve had when I tested positive in the past. What would cause these flares and what tests should I ask my new doctor to run to get to the root cause of this?
