I keep getting a low grade fever of about 99.7 with no other symptoms besides a headache every once in a while... I can get it to go away with some tylenol and a nap but Im not sure if I should be concerned with it or not. At first I thought I was getting a cold or something but after about 4 days of it and no other symptoms Im completely lost! Anyone else delt with something like this? I have an appointment first thing tomorrow Im just curious as to what it might be?
