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. im not sure if these are symptoms of any STDs out there.
