I am a twenty year old gay male and I recently had anal sex. About an hour after I was feeling pain sort of in my kidneys...I have kidney stones...it was sort of that pain, though I don't think the pain was my kidneys. I also experienced blood in the first bowel movement after, intense chills/shivers, tightness...sort of like I was flexing my abdominal area, uncontrollable twitching in my abdominal area, and pins and needles in my hands. I sort of felt like I had been drugged cause I was a little disoriented. I accidentally feel asleep while laying down...I didn't want to just in case it was serious, or I had internal bleeding, but when I woke up in the morning, it was gone. Until a few hours later while I was at work. The shivers and twitching were gone, I just had pressure and pain in my abdominal area. I also experienced a few seconds of sharp pains in my pelvic area. I am very worried. I just moved out of my parents house, so I have no insurance, so I don't know what to do. Please! I need advice!
