Hard Lump on my Rectum. Please Help.
Let me first say that I do not know a lot about colon and rectum health, so I am hoping that someone here can help me.
I am 26, male, a non smoker, I don't drink and I eat a balanced diet. I am slightly overweight, but mostly healthy I think. About a week ago, I developed pains inside me, right near my anus. I don't have any bleeding, trouble going to the bathroom, blood in my stool, weight loss or anything like that. What I do have, and my wife confirmed this, is a hard lump on my rectum, about two inches inside, on the wall of the rectum on the right side. It is not inside, not a hemorrhoid I don't believe, you can only feel a hardness of the wall itself, while on the left side it is stretchy, and not painful. It hurts from the pressure when I have to go, but I don't have any trouble going, and no diarrhea or anything. It feels like it may be outside. The right side is hard and painful. When I sit, I can feel the pressure inside, although it is not terribly painful.
What do I do about this? Should I wait and see if it goes away? What sort of doctor or tests do I need?
Any help is great. Thanks all.
