I ve had a low grade fever for 2.5 months now along with headaches lasting a few days to a week and fatigue. The low grade fever is 99-100.2. I ve seen my PCP and had blood with ruling out infection including anaerobic infection and autoimmune disorders. He has referred me to an infectious disease specialist but the wait is a few weeks and I m worried to wait that long. There has been no mention of what it could be. OTC pain management doesn t help the headache or bring down the fever. Does this sound like cancer? All I can think of at this point is chronic fatigue syndrome or cancer. I also spoke to a nurse and told her about the fever and she simply said I don t have a fever and to take Tylenol even though I told her it doesn t work. The headaches are from a dull ache to throbbing. I recently even got glasses to try to help the headaches and nothing changed. Please give me advice.
Fever is defined as temperature greater than 100.1 Fahrenheit.  Check to see how high the temperature is and if it is highest during daytime, nighttime, or every couple of days.  Have you travelled anywhere during the last 2 months? Some infectious diseases are more common in certain areas.  Have you taken any new medications?  There is a possibility of Chat Doctor.  Chronic fatigue does not cause a fever, so that can be ruled out.  Do you have any other symptoms such as rash, itching, stomach pains, etc. You are correct that some types of cancer do cause a fever, but those conditions are pretty rare? Best regards
