External hemorrhoids "- Perianal thrombosis (Thrombosis Periana)
Hemroids are the most commonly used term in proctology. It is often said that there are "internal" and "external" hemorrhoids - it's a big mistake and error, which unfortunately remained current in medical circles. Hemorrhoids can be "just" piles, simply because there are no internal or external.

What is often called the "external hemorrhoids" is actually a perianal thrombosis, which does not have any anatomical location or connection with hemorrhoids.
Perianal thrombosis caused blood clotting in the small superficial veins under the skin near the anus, resulting in the creation of the node at the edge of the anus, which can be the size of grains of wheat to a size medium large walnut.
These nodules make the skin taut, causing pain, then they are often blue, and even may spontaneously rupture, leading to a greater or lesser bleeding. Usually occur suddenly, almost overnight.
Most authors agree that the occurrence of perianal thrombosis responsible slowed the flow of blood through the veins of the anus (called venous thrombosis), and it contributes to pregnancy and menstruation, as a response to endocrine (hormonal) effects.
Also, biking, and more seating as well as difficulty emptying contribute to venous circuit. Generally speaking, still not fully understood the cause of the emergence of perianal thrombosis.
