My anus appeared a small lump of excess flesh when defecating, there was a sharp pain, the stool was quite large and hard, there was a time when there was blood but then there was no more. There is no fissure around the anus, and there is no pain or redness to the touch. Recently, I have been eating a lot of fiber and drinking a lot of water, the stools are also soft and less hard, but it is still quite painful when defecating. So the doctor asked me if I had a lump in the anus, what is the cause of painful defecation? Thank you doctor.
