What is the typical presentation of a thrombosed external hemorrhoid?

In the case of a thrombosed external hemorrhoid, patients typically present with severe pain and swelling. This condition arises when a blood clot forms in the external hemorrhoid, leading to acute inflammation and significant discomfort. Patients often describe the pain as sharp and debilitating, and it can be exacerbated by movements or straining.

The swelling is usually visible externally, often appearing as a firm, bluish lump near the anal opening. The intense pain experienced during a thrombosed external hemorrhoid is a key characteristic, distinguishing it from other conditions, such as simple external hemorrhoids, which may not cause as much discomfort and can often be non-tender. Other potential symptoms, like itching or a painless lump, are more commonly associated with less severe forms of hemorrhoidal disease or other anal conditions rather than a thrombosed external hemorrhoid.
