Rest/leaving it alone is probably the only fix w/o popping. I do know Nolan Ryan used to soak blisters in pickle juice. Moises Alou soaked his in urine. Seriously. I'm not sure if they popped them before doing it though. As for bowling, when I had blister problems, and they were bad, I would pop them then throw some Robbies skin patch on them. Can't say I miss that stuff. Feel the burn, baby!!!!!
