I had unprotected sex with a close female friend of mine at the end of December. I am in a long term relationship so immediately after the experience i began to worry about contracting an std. without fail i began to get a burning sensation when urinating. my doc checked me out, i had no visual symptoms but he put me one meds for clamidia and gonorrhea just to make sure if i did have anything it was treated. at the beginning of feb my throat was extremely sore and my neck felt tight. i went to the doc again, was running a low grade temp and he put me on antiboitics. i asked if this could be related to symptoms of an std and he said no. the antibiotics helped slightly but the symptoms never completely went away. i went back to the doc a week and a half ago to explain that my throat still felt sore, and i had pressure in one of my ears. he confirmed that my tonsils were slightly swollen, i had fluid in my one ear indicating some type of infection, and i was still running a temp of 99. he prescribed cyprofoxacin, another antibiotic. currently my throat and ears feel much better, but i have pain in my lower joints, particularly my knees and buttox. I've taken the HIV rapid test twice, both times coming up negative. I should also note that the woman i had sex with had a full std test and everything came up negative. I have never showed any physical symptoms around my groin, but from doing research on all the std's physical signs don't always appear. However my problem is that every symptom i get in every area of my body i relate to my encounter with her, and worry that i have some type of std or hepatitis. If you could provide any feedback to calm my nerves it would be great.
