Full Answer

The symptoms of hemorrhoids include feces leakage, discomfort, irritation in the anal canal, painless bleeding and swelling. Veins can swell around the anal region to form either internal hemorrhoids or external hemorrhoids. The symptoms and method of treatment will depend on the type of hemorrhoids that a patient has. In some cases, a patient can suffer from both types of hemorrhoids, notes WebMD.

Internal hemorrhoids cannot be seen or felt, and do not cause any discomfort. However, they can bleed when they are irritated due to bowel movements. In some cases, an internal hemorrhoid can come out through the anal opening, and this is referred to as protruding hemorrhoid, explains Mayo Clinic.

External hemorrhoids are usually outside the anal canal and can also bleed when irritated. In some cases, external hemorrhoids can cause a blood clot, which leads to severe pain, inflammation and swelling. It is necessary to see a doctor when there is bleeding in the anal canal.
