Can anyone help me please? I feel like im going mad, cant eat, cant sleep and dont have any tests for ages :( My problem is I have a throbbing/pressure pain in my rectum - it burns and i also have a very bad back because of it. Can anyone tell me if its a symptom of IBS? I did a poo this morning and it was around 3cm wide. Is that normal or should I be doing bigger ones? Also, I have just been told i have a 'retroflex' uterus. Could this be causing the pain? HELP. Im so scared i have colon cancer its unreal. Please help me. xx
