In some hemorrhoids that develop around your anus, blood can collect and form clots. Intense pain is often the result. Warm baths, witch hazel compresses, and nonsteroidal anti-inflammatory drugs (NSAIDs) can be used to relieve the pain. The clots will usually go away on their own in 4 to 6 weeks. If the pain is too severe to wait, however, your doctor can make simple incisions to get rid of the clots.
