There is a bag next to the anus, which is hard when pressed. It hurts a little when you press it, but it doesn't hurt at ordinary times.

There is a lump in the anus, and there are many possibilities, such as thrombotic hemorrhoids, anal submucosal abscess, rectal polyp or anal papilloma, and even rectal tumor. Depending on the specific clinical manifestations, if it is thrombotic hemorrhoids, the mass is usually small, with obvious tenderness, elastic texture or soft to the touch. However, if it is a submucosal abscess, the mass range is relatively large, and obvious fluctuation and tenderness can be felt during the suppuration period. And if it is anal papilloma, the lump is hard. If it is a rectal polyp, the texture is generally soft, and it is easier to bleed when it comes into contact. If it is a rectal tumor, the mass is usually slightly larger, feels like cauliflower, and it is more likely to bleed when it comes into contact. There may be dark red blood on the surface of stool, or even blood mixed with stool. What is the specific situation, you need a doctor to conduct a specialist examination before you can distinguish it in detail.
