Last year on 12 November I slept with someone I met and we used protection vaginal sex and we kissed numerous times. We both took a rapid test and both results were negative before sex. first week of December i started having chest & back pains, burning nose and a persistant tension headache...I got sinus medication but it did not help much. I took another rapid HIV test on 27th December which came out negative then I also did a lab COVID test (it was a mouth swab) results came back negative. today January 21. its been a month and I am still having a persistant tension headache which does not respond to pain medication, and i still have burning sensation in my nose plus chest and back pains. my doctor gave me more pain medication and GERD medication but its not helping either.
