I have been feeling feverish since beginning of Jan2018, my normal body temperature is around 97.5 but when i feel feverish it reaches 98.6 (I know this cannot be called fever). But my forehead, face, legs become very hot for that duration when i feel feverish. This happens to me 2-3 times every day for 30 mins to 2 hours. Then beginning of Feb2018, I got rashes on my arms, legs and lower abdominal.
The doctor prescribed me allergic medicine - Prednisone, the rashes went away in 4 days but feverish feeling continues.
I got myself tested for all STD's and it came out to be negative.
Specifically, i tested for HIV 4 times:
1) 28 Dec 2017 - 4th generation negative
2) 25th Jan 2018 - 4th generation negative
3) 7th Feb 2018 - 4th generation negative
4) 7th Feb 2018 - HIV1 RNA, QL TMA - Negative
My last sexual encounter was on 31st July 2017
Just wanted to make sure its nothing to do with HIV?
Also, what else could be the reason for this low grade feverish feeling?
