Hello, I have a small hard bump on my left butt cheek. It looks and kind of feels like a pimple, but when I try to pop it nothing but blood comes out of it. I have put alcohol on it as well hoping that will help. I never had this before, so I m just curious as to what it may be. Its not very painful, and has gone down in size since I popped it. Is there anything else I should do to it, or anything I can do to prevent it from returning? Thanks
