I once went to the hospital because my penis was touched by lady while i had a few scratch on it and feared she had cut on her hand,although i have never had sex but after 3 months i went to the hospital because i was having some hiv sypmtoms,my mom followed me to the hospital to do a test and she even assured me that nothing is wrong with me,after the test the result is negative and i could still remember that before i went for the test while i was playing with my little brother,i noticed that he got some blood on his leg from my injury,some week later i noticed he started having some unexplained small injuries that let some few black spots,i know i don't have hiv but i just feel like am going crazy,few months later after i did the test,while playing ball i had an injury on my palm and while i went outside i shook hands with some guys and am scared because i don't know their status then the fear of hiv resumed again,whenever i shake hands with people i check my hand because i fear i might have gotten some blood on my hand from the person i had an handshake with,there was another day that my saliva touched my brother's wound,now am just scared because my brother has been coughing and the cough is going to a week now,i have been having a small swell in specific area at the lower part of my neck,that swell is gone now but another small swell has come in a different area on my neck.Please i wish i would find help here,am about to resume for school now and am scared i would not be able to concentrate.AM GOING CRAZY PLEASE!
