Hemorrhoids bleed and itch in some cases, says Mayo Clinic. Patients do not usually see or feel hemorrhoids located inside the rectum. However, strain and irritation from passing stool sometimes damage an internal hemorrhoid and cause it to bleed.
Straining sometimes also causes an internal hemorrhoid to be pushed through the anus, according to Mayo Clinic. The symptoms of this protruding, or prolapsed, hemorrhoid include localized pain and skin irritation.
External hemorrhoids lie under the skin around the anus, and symptoms include bleeding and itching, states Mayo Clinic. Other hemorrhoid symptoms are swelling or a lump near the anus and leakage of feces. Rectal bleeding associated with hemorrhoids is usually minor and not cause for alarm. However, a doctor's diagnosis to rule out other causes of rectal bleeding is beneficial, especially if other gastric symptoms are present.
