Since about 1 year back I have been experiencing intense pain attacks in the walls of my rectum. The pain always lasted for 1-2 seconds and didn't return before a week or longer so I didn't bother looking it up, thought it was nothing serious. However, when I ate a few protein bars over a few days and got constipated, I suddenly experienced the worst rectal pain attack I've ever felt, like a knife stab into the rectum. And following that day, I have been experiencing regular rectal cramps everyday (although not as intense pain as when this started) for 2 months now. It hurts the most when I walk and relax the muscles in my rear, it also tend to hurt when I lie down relaxing, which causes trouble sleeping. It's as if my rectum is constantly swollen or "heavy" like it weights more than usual. I would also like to describe the sensation as "pressure" but it's not like it feels like I'm gonna have a bm.
I have been to the doctor and received a colonoscopy examination, a blood sample and had x-ray scans taken, but they simply cannot detect anything wrong.. Everything seems to be normal in my body, even thought it's obviously not. I don't know what to do, I miss my life without pain so much. Do you have any ideas?
I was worried the pain it's due to me having anally masturbated too much/rough, but I can't seem to find a link no matter I how much I search on google, sure obviously anal penetration can cause pain, but chronic pain and pressure? I also never injured myself or felt considerable pain during the intercourse, if I ever saw any blood it would be minor stains and stop bleeding immediately. I have read up on people having seriously injured their rectum through mastubation but have not not seen any records of the specific condition I have. It seems like my problem is unique in the world and that it's never going away, im so sad.
