I had vaginal intercourse with European sex worker. During the intercourse conform broke off. I am not sure, but I think i was having sex for like 5-10 mins after condom broke. I am really scared and really worried if I have catched HIV. Feeling very bad and regretting why I went to do this stupidity. It s been 18 days since this incident and on 9th day, I got very terrible pain in my lower back neck for like 2 days. I used pain relief tube to get rid of the neck pain, but I could still feel the pain for like 6 days. On the other hand on 10th day, I also got loose motions just once. On 18th day, I have got small alcer in my mouth. Are these symptoms related to HIV? Do You think, I am at risk? FYI, Nurse has given me hepatitis b injection on 7th and 14th to be more protective from other STD.
