hazel

I just got back from a 3 hour practice with my orchestra and my just healed pizzicato finger has a new blister. I have to get to another event in an hour and I'm worried that my blister will pop when I go to play this one peice I want to play that has 57 measures of forte pizzicato before it switches back to arco. Any tips to help me fix this or prevent this from happening in the future?
