A lump in the anal canal or around the anus that feels swollen is most likely a hemorrhoid. It is important, however, to be evaluated by doctor in order to be diagnosed. Hemorrhoids are common, especially in individuals with chronic constipation. Hemorrhoids are actually normal bundles/networks of small veins in the anal region. Everyone has them, however when we speak of hemorrhoids in medical terms, we usually talk about symptomatic hemorrhoids. There are mainly two types of hemorrhoids that exist. Problems with Internal hemorrhoids don't usually cause pain, however they may present as large, dark purple lumps that prolapse through the anus. They may bleed or itch and change in size. External hemorrhoids don't generally bleed, however they can be extremely painful and debilitating. Treatment ranges from over the counter creams (e.g. Preparation H) and diet modification to surgical procedure to remove the hemorrhoids. It is recommended that you be evaluated by a Colon and Rectal Surgeon, or a General Surgeon for this problem. These are the specialists that usually handle peri-anal problems. With a quick office examination, they can accurately diagnose whether or not the lump you are feeling is a hemorrhoid. If it is a hemorrhoid, then the type of hemorrhoid and the appropriate treatment can be recommended.
