For a couple months now, I've noticed I occasionally have small bumps around my anus. They are near the back of my vagina, on the inside of my left butt cheeck. I have nothing on the right side. There is maybe one bigger bump (the size of a pencil's eraser) surrounded by two or three smaller ones and is the color of my skin. It looks like a small swollen mosquito bite when I scratch it. It has no fluid/pus in it; it hurts and kind of stings when I touch it. These pimples kind of feel like a rash; they hurt when I touch them. It doesn't hurt to sit or stand or walk. They go away for around a month, and come back. Maybe it's sweat that's making me get the rash? Or an std? Any help would be great. Thanks.

Unfortunately, as I cannot actually examine patients on this forum, I generally cannot offer a specific diagnosis.

There are many potential causes of inflammatory skin masses near the anal opening (most of them, thankfully, are not due to cancer).

You would be best served by having your doctor take a look at these lesions.
