Distended, swollen or inflamed veins around the anus (external hemorrhoids) or in the anus (internal hemorrhoids) can cause symptoms ranging from painless bleeding to minor itching to pain.

The classic symptom of internal hemorrhoids is painless bleeding, most often noticed as bright red streaks on toilet paper. Blood can also be found on the stool, underwear, or in the toilet bowl.

External hemorrhoids are more likely to cause pain and itching. They may bleed as well. A blood clot may form in an external hemorrhoid. This is known as a thrombosed hemorrhoid, and can be quite painful. It often feels like a hard, painful grape-like lump on the anus. With conservative treatment, these usually resolve. However, these may need to be removed surgically.

Hemorrhoids are a common annoyance for adults. According to the Mayo Clinic, about half of adults have had a hemorrhoid by age 50.

The good news is that hemorrhoids are generally not dangerous, can be easily treated with natural remedies, and often go away within a week.
