When a patient has external hemorrhoids, they will lie under the skin around the anus. They can become very itchy and may bleed. Sometimes, the blood may accumulate and form a thrombus (clot), which can be painful; the area will swell and become inflamed. External hemorrhoids are more likely to present with pain.
Hemorrhoids (US English) or haemorrhoids UK /ËhÉmÉrÉÉªdz/ are vascular structures in the anal canal. In their normal state, they are cushions that help with stool control. They become pathological or piles when swollen or inflamed. At this point the condition is technically known as hemorrhoidal disease. The signs and symptoms of hemorrhoids depend on the type present. Internal hemorrhoids usually present with painless rectal bleeding, while external hemorrhoids may produce few symptoms or if thrombosed significant pain and swelling in the area of the anus.
