I have only done 4 flushes so I am not so experienced with stones myself, but I do know a little about hemmorroids. I had a "lovely" one after I gave birth to my son. The midwife gave me witch hazel pads. My hemmorroid was small and not bleeding but it was uncomfortable. The witch hazel brought a great deal of relief! If you can not find already made pads, you could probably just get a bottle of witch hazel and make your own pads with gauze or something. It is a very refreshing feeling- takes away the burning and itching, atleast for awhile!
Good luck and congratulations on getting that nastiness out of your body and into the toilet where it belongs!!!
