My band practiced for four hours tonight and I got a blister on my right middle finger, popped it (as I was playing), got another one, and got one on my index finger. We're performing twice tomorrow (I'm also playing with another group so three times, total) and I have the last lead in the last song and don't want to ruin it.
As it is, I'm not sure I'll be able to play as well as I normally can due to the blisters so my question is if there's some way I can get rid of them, make them stop hurting, etc. by the time we play tomorrow.
