A painless red swollen bump around the anus that has been present for 3 days without itching is most commonly an external haemorrhoid (pile), a skin tag, or a small cyst. These are very common and are generally not dangerous. An external pile can appear as a soft, reddish swelling around the anal opening, especially after straining, constipation, or prolonged sitting. The fact that it is not painful and not itching is a good sign.
