Swelling of External Hemorrhoids
External hemorrhoids have the potential to develop thrombosis, a condition where a blood clot forms within the hemorrhoid. This clot can block the blood flow, leading to severe swelling and enlargement of the hemorrhoid. In such cases, thrombosed hemorrhoids can protrude from the anus. Despite aggressive treatment, it may take several weeks for the swelling to subside, and in some cases, surgical intervention may be required to remove the thrombosed hemorrhoid.
Pain
When a hemorrhoid becomes thrombosed, patients often endure intense pain. This pain can be triggered by various activities, such as sitting on flat surfaces, urinating, and passing stool. In certain instances, individuals may even experience ongoing pain while standing. Thankfully, over-the-counter medications are usually sufficient to alleviate this symptom. Typically, the pain subsides within three to four days. However, if the pain persists beyond this timeframe, it is advisable to consult a doctor, as surgical intervention may be necessary.
