Well, it could be random; people with no medical problems at all get these thing. It could be related to my UC. It (really really probably not) could be that I actually have Crohn's, and am going to be prone to these. Several things lead me to believe that I don't have Crohn's, though.
What I really think it is, though, is that I started using a different brand of mesalamine enema. I've always had Perrigo in the past, but an insurance switch (and therefore a different mail order pharmacy) resulted in me getting Garvis enemas. I started using them a couple of months ago, and noticed that the tips on some of them are rough. I've definitely felt a few "pinches" when using them. Anyway, a quick google search of "enema perianal abscess" turned up a few websites that list "enema tip abrasion" as a cause for abscesses.
Yeah, I'm mad. I'm for sure not using any more of those enemas and am probably going to call them and chew someone out. In my nice, frigid, don't eff with me voice that I have.
