Hemorrhoids, also known piles, are swollen veins in the anus and lower rectum. Hemorrhoids are similar to varicose veins. Hemorrhoids can develop inside the rectum, called internal hemorrhoids. They also can develop under the skin around the anus, called external hemorrhoids.
There are several options available to treat hemorrhoids. Many people get relief with home treatments and lifestyle changes.
Symptoms
Symptoms of hemorrhoids usually depend on the type of hemorrhoid.
Internal hemorrhoids
Internal hemorrhoids lie inside the rectum. You usually can’t see or feel them, and they rarely cause discomfort. But straining or irritation when passing stool can cause:
- Painless bleeding during bowel movements. You might notice small amounts of bright red blood on your toilet tissue or in the toilet.
- A hemorrhoid to push through the anal opening, called a prolapsed or protruding hemorrhoid. This may result in pain and irritation.
External hemorrhoids
These are under the skin around the anus. Symptoms might include:
- Itching or irritation in the anal region.
- Pain or discomfort.
- Swelling around the anus.
- Bleeding.
Thrombosed hemorrhoids
Blood can pool in an external hemorrhoid and form a clot, called a thrombus. A thrombosed hemorrhoid can result in:
- Severe pain.
- Swelling.
- Inflammation.
- A hard, discolored lump near the anus.
