Hemorrhoids (Piles) are swollen varicose veins located around the anus or in the lower rectum. About 50 percent of adults in Minnesota and Florida experience the symptoms of hemorrhoids by the age of 50.
Severe pain is actually not a common symptom of internal hemorrhoids, because internal hemorrhoid happens in the area above the dentate line that is supplied by the visceral nerve, like those found within the intestines, which sense pressure and dull discomfort rather than sharp pain. Many patients have mild irritating pain in their rectum periodically, especially when it has a flare-up.
In general, symptoms of external hemorrhoids are different than those of internal hemorrhoids. External hemorrhoids can be felt as bulges at the anus, but rarely display any of the same symptoms seen with internal hemorrhoids. They will cause problems, 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 and often requires medical attention. The somatic nerve in the anal canal (below the dentate line) can sense pain, this is why the patients feel significant pain when they develop thrombosed external hemorrhoids. Thrombosed hemorrhoids may heal with scarring and leave a tag of skin protruding from the anus. Occasionally, the tag turns out to be quite large, which can make anal hygiene (cleaning) difficult or irritate the anus.
