Hey all, I had some good callouses on my playing fingers in the right hand built up. I was doing gigs and playing pretty often with no problems. Then after a long gig playing harder than usual, new blisters opened up. Now, more than a month later, im still dealing with new blisters. I play every day and have tried popping and keeping them, but old ones keeping giving ways to new ones. Any advice on how to prevent this?
