So i posted about a week ago about a boy i was dating who i had unprotected sex with about 3 times and protected sex 3 times with but he never came in me and a few weeks after I found out that he had a girl friend who he was having sex with during our time together and during their 3 years together he cheated on her several times... A few weeks after I had diarrehea for about 2 days my lymph node in my underarm hurt for about a day at some point during this time and I had a sore throat for about a day and a cough and a stuffy nose that came with it that lasted about 2 weeks, it is possible that i may have a had a fever at some point during this time ...My head also hurt one night during this time and recently my upper back has been hurting me. Also during that time I woke up with night sweats twice and this was before I started researching hiv syptoms so it wasnt psychological or anything...also i have to pimples under my arm...are these hiv symtoms and should i be worried?
