I take sitz baths 3-4 times a day, around 20 minutes each. Does anyone know the rule on this -- if I take more, or take longer ones, will it help more? If the warm baths help with circulation down there, I would think taking longer baths might help more. My gut tells me, though, that if you take too many short ones, you might risk drying the bum out a little too much.
I read an account of someone taking hour-long baths (http://boardsailor.com/jack/af/patient_6.htm) and it helped.
Personally, I'm willing to quit my job, fly to the caribbean, and float naked in the ocean all day if it'll help get rid of this thing. (Just need to win the lottery first.)
