I am a 60 year old woman with no serious health concerns. About a month ago I had a cold and sinus infection which I took antibiotics for .Three weeks ago I had the flu
bug that is going around for two days. My concern is: for the past two weeks I keep spiking a temperature. In the morning when I wake its normal; by afternoon it is up to 99-100.8. The fever will stay until I rest again. Any suggestions on what it could be?
