I have been getting low grade fever , up to 99.2 degrees for the past 3 days. It feels that there is thick mucous in my throat , but nothing comes out. Also last night, I did sweat a lot, the room temperature could have been a bit high as well and I was wearing a sweater and had a blanket on. I did notice that the fever went away at around 6 pm last evening and came back after around 16 hours again.
