Question I never thought I'd ask...?

I've had a small red bump on my butt, close the anus, for over a month and I have no hypothesis what it is. Its not painful at adjectives and there's only one of them, but I've notice that its very slowly gotten a moment or two bit larger. I haven't had sex since September because my husband's surrounded by Iraq, so I don't think its sex related...but I could be wrong. Any thinking what it could be? It could be a hemorrhoid, or an ingrown hair, or a sebaceous cyst. (The hemorrhoid would increase after staining to move your bowels. The hair would be slightly aching to touch. The cyst would feel tough inside, like a morsel of something trapped under the skin.)
If it's growing, see your doctor just about it. It's always easier to treat problems impulsive.
Sounds like I don`t know a hemorrhoid...don't try to pick it. Go to a gastroenterologist or a proctologist. Sometimes they can put medical rubber bands on them and they die of no circulation and leak off...sometimes they do surgery and sometimes creams are used.
