An infection may also be to blame.
An occasional “pimple” on your backside isn’t a big deal. Even a bum full of tiny, fine, red bumps isn’t anything to worry about, so long as they aren’t painful, super itchy, or getting worse.
But sometimes pimples on the butt are caused by a bacterial or fungal infection. Staph is a likely culprit.
So, if you have a pimple that gets really big, or one that hurts badly, you should give your doc a call. Same thing if you have many very inflamed pimples across your derriere.
Of course, if you have any doubt as to what is causing the pimples on your buttocks, it’s a good idea to have a physician check it out.
