Well, I had one as a resident (only hemorrhoid of my life, and, boy howdy, it HURT - the literal "pain in the ass"), and sucked it up. A colleague offered to open it (not for my relief - because it's a required procedure in residency - you have to do 1), but I declined. After 3 or 4 days, I was all right.
Now, what to do? I didn't actually have to consider it until I was an attending. First was a lady the day before Thanksgiving. I just happened right at that minute to have a general surgeon in the ED, and I asked him to take care of it, and he did, and literally taped this lady's ******* shut. She was bummed she couldn't eat for Thanksgiving, because she couldn't ****.
The second was another lady in the same community ED. This one wouldn't even let me near her ******* because it hurt so much - barely got to look at it. I was going to have her see general surgery the next day, and I called the GSx on-call to tell him that. She wasn't bleeding, and her vital signs were stable, and I told him he didn't have to come in, but he did (to this day I don't know why, except maybe he knew something I didn't). After he sees this lady (and she had lidocaine jelly applied to her butt), he says, "Good thing you didn't cut on that - it's not an external hemorrhoid, but a huge internal hemorrhoid that is protruding".
So, cautionary tales. I don't think you can go wrong with Colace, fiber, and f/u with GSx. If they're external, no big deal.
