Dang, lot of pisser problems round here. I never had stones, but had pretty sever bladder pains for years so I feel for you guys. I finally got that under control. For me it was food intolerances and some nerve pain from heavy leg training in the gym. It was bad at times.
Hopefully everybody will have a healthy piss plumbing next year.
