Hemorrhoids and Symptoms
While piles are not life-threatening, they can bleed, itch and become swollen or inflamed if left untreated. Hemorrhoids can be felt or seen as lumps, but not if they remain inside the rectum (internal hemorrhoids).
The most common symptom of internal hemorrhoids is the presence of bright red blood in the stool (rectal bleeding). If an internal hemorrhoid is near the anal opening, it may become prolapsed (protrude through the anus outside the body), causing irritation and pain.
Internal Hemorrhoids vs. External Hemorrhoids
Internal hemorrhoids are located just inside the anus, at the beginning of the rectum. They usually don't cause discomfort. But when prolapsed, they can be painful.
External hemorrhoids occur at the anal opening and tend to be painful.
Symptoms of external hemorrhoids may include painful swelling. Blood clots (thrombosis) may develop, resulting in a hard lump around the anus. This may cause severe pain and usually requires immediate medical attention.
