SYMPTOMSBurning, pain, itching, inflammation, swelling,
irritation, seepage, and bleeding. CAUSESHemorrhoids are
enlarged varicose veins, found in the anus and rectum. Those
occurring below the internal sphincter (a circular muscle which
closes the rectum) are called external hemorrhoids. Those above
that sphincter are called internal hemorrhoids. Internal
hemorrhoids are generally painless, but often bleed. When they
do, the blood is bright red. External hemorrhoids are also
called piles. Sometimes they protrude from the anus. Because
they enlarge and lose their elasticity, they often form little
sacs which protrude into the anal canal. The skin above them
turns blue or purple and can be extremely painful. A prolapsed
hemorrhoid is an internal one which is protruding outside the
anus. Often there is a mucous discharge and heavy bleeding. They
can be very painful. When they bleed, a fair amount of blood can
issue forth. But it does not indicate a serious disease. Older
people are more likely to have them. Pre
