Male 32 years old, does not smoke, does not drink alcohol. Yesterday when I went to the toilet, I had pain in the rectum during the passage (like a big burn) and small burn afterwards. Today, I didn't have pain during the passage but a little burning afterwards and on the stool there was like mucus with red inside, on one side of the stool. It was like a long straight line, it was not scattered everywhere. I don't seem to have external hemorrhoids, but internal maybe? This is the first time this has happened to me. I also have the other symptoms of internal hemorrhoids, like the feeling of having a wet anus. Often blood is mixed with mucus. What do you think about it?
