Ouch!! rosebud...
Sounds like you've had it bad, the pain levels must of been off the scale..
I believe in sitz baths too, after my surgery I had 4-5 baths a day which really did help with the pain, I also put Epsom salts in the water, it's a well know healer! as for the wiping I only ever dabbed with cotton wool balls dipped in luke warm water then dried off with a hair dryer. Fibre can be a bad thing, especially if you're not getting enough water with it, I was taking a fibre supplement but not drinking enough water and the stools were too big and hard, which, I think have contributed to my recent tear, my conclusion is to stick with the Movicol and a load of water.
