So for the past 4 months I have had stabbing pain in my rectum, it's an internal pain. The past 4 weeks it has got so much worse to the point that sitting on my bottom in to painful I am unable to do it. I have also started to have diarrhoea in the past weeks. The pain is now migrating into my abdomen so it just started in the rectum and now it is in rectum and abdomen. I have seen my gp they did a rectum exam and said nothing was wrong I had no internal or external piles, no tears nothing. So she said I was fine. I'm concerned because it is getting worse and not to sure what to do? Any advise would be helpful. Thank you
