Sounds like 'roids to me. I have them, too. Same symptoms (itchy ass, blood on the paper after wiping, etc.). Just keep a supply of Tucks or Preparation H handy. And keep the brown-eye clean as you can.
I’ve found that run-ins with the runs (gotta love anxiety disorders (mostly under control, thank you very much)) will tend to make the 'roids return.
An important thing to remember is that if there’s dark blood on the toilet paper, that’s big trouble (as in tumor). Bright, fresh blood is probably not too serious, especially if it’s accompanied by irritation.
Tucks, baby.
I had a similar problem after childbirth and used Preparation H and I swear for the next week and a half I wanted to die. It like, ate the skin off my ass or something, I was SO RAW. I’d cry every time I had to go to the bathroom and I’d have to run to the bathtub afterwards and soak my butt in some hot water, which soothed it.
Tucks. Tucks Tucks Tucks! Preparation H bad. Very bad.
Bara’s blood rule of thumb is good but don’t get TOO freaked out if it IS dark red. I know people who have had that for years and nothing’s wrong. If it’s dark red, just call your doctor but don’t lose any sleep worrying.
