Causes and Treatment for Piles
'Hemorrhoids' is the medical term for the condition more commonly known as Piles. They are a mass of swollen rectal or anal blood vessels. These veins are situated in the lower part of the anus and rectum. Hemorrhoids are of two types:
1. Internal 2. External
Internal hemorrhoids lie deep inside the rectum and are not normally visible to the naked eye. They don't usually hurt, but their presence is marked with the symptom of bleeding through the anus.
External hemorrhoids get formed in the anal region and create discomfort. When an external hemorrhoid protrudes through the anus, it can be seen and felt. Sometimes blood clots can form within the mass that slips down; it can be extremely painful.
