Rectal pain is a common sign of anorectal diseases in Minnesota. It can be caused by various conditions. Pain caused by an acute anal fissure may occur during intense, forced bowel movements that are often accompanied by rectal bleeding. Pain that begins gradually and becomes excruciating may indicate infection. In general, external hemorrhoids don’t cause significant rectal pain in Minneapolis and St Paul. They will cause pain, however, if the varicose vein complex ruptures, as blood clots occur and build up the pressure inside the lump. This condition, known as thrombosed external hemorrhoid, causes an extremely painful bluish anal lump. The somatic nerve in the anal canal (below the dentate line) can sense pain, this is why the patients feel significant pain with the immediate onset when they develop thrombosed external hemorrhoids.
Internal hemorrhoids, however, are not painful due to being located above the dentate line of the rectum that is supplied by the visceral nerve, like those found within the intestines, which sense pressure rather than pain. Similarly, rectal cancer typically does not cause pain unless the condition is advanced. The patients with chronic anal fissures usually have intermittent sharp rectal pain and bleeding with each bowel movement for a long time.
Proctalgia fugax (rectal pain) is a more serious anal pain condition that involves short spasms of intense pain. This condition may occur once each year or up to three or four times each week. The pain is typically accompanied by sweating and an urge to pass stool. There is currently no treatment for proctalgia fugax, but placing oneself in warm water may provide symptomatic relief.
