Hemorrhoids, commonly known as piles, represent enlarged veins in anal canal (external piles) and may involve lower rectum as well (internal piles). Both internal and external can occur together as well.
This is a very common condition. Some do not even have symptoms while for others it can become a severe problem.
Signs and symptoms of hemorrhoids usually depend on the type of hemorrhoid.
External hemorrhoids
These are under the skin around your anus. Signs and symptoms might include:

If you have bleeding during bowel movements or you have hemorrhoids that don’t improve after a week of home care, talk to your doctor.
