My band played for a quick 40 minute set (we were one of 4 bands) last night. I figured since we were only playing 40 minutes I'd give 'er to the max. We played a great set, but now I have some pretty brutal blisters on my plucking fingers. I asked my wife if I should pop them, but she said no. I have a 3 hour rehearsal tomorrow night, gig Friday and a gig Saturday so I really need my fingers healed. Any ideas?
