WHAT MAKES HEMORRHOIDS CAUSE RECTAL PAIN?
Hemorrhoids are generally not painful. Pain arises from excessive irritation or from thrombosis. Thrombosed hemorrhoids occur when blood clots form in the hemorrhoidal tissues. It is a very painful condition and is preceded by a bout of constipation or diarrhea. When internal hemorrhoids form blood clots and get trapped outside the anus, with an associated spasm of the sphincter, they are referred to as strangulated hemorrhoids. Whereas internal thrombosed hemorrhoids may require hemorrhoids surgery, external thrombosed hemorrhoids have a tendency to clear up on their own in a few days, but some cases may actually require removal of the clot.
