Hi, I have been forced to have anal sex for couple of years, Ive never like it and never enjoyed it, and was always painful to me, the problem is lateley I experienced some bleeding during bowel means when am emptying just at that moment and the blood disappear right after that, I dont feel any pain in the anus but I have a horrible right lower abdomen that doesnt let me live normally it is painful when am standing lots or sitting lots so uncomfortable, feels like burning inside my colon,I am so worry and feel so embarassed to talk about it with my PCP, I am so sfraid that I developped infection or cancer, I mention here that I used to suffer from constipation long time ago because of emotional stress and used to have a stress gastro-duodenal ulcer that I treated 15 years ago..please are these symptoms means a cancer/

### output:

Hi. Thanks for your query.First the most important thing is if you do not like the anal intercourse, you have to say no to it by all means, as this is causing you psychological as well as physical trauma. The bleeding with the stool and without pain is suggestive of the Hemorrhoids or piles. This is due to the fact that due to anal intercourse the tissues supporting the veins get loosened up allowing them to swell. The pain in the right abdomen can be due to colitis or IBS which you must also be suffering already. This does not look to be cancer as there will be mass at the rectum, or the anal canal. I would advise you the following.::Talk to your PCP, Get a reference to the Surgical Gastroenterologist. Get ano-proctoscopy and colonoscopy and biopsy to see what the exact problem is like. Once the diagnosis is made further proper treatment can be very well planned. If there are large piles get operated, if small get the proper medication. Have Site bath twice daily. No anal sex at all.
