I don't have any problem with my finger tips. It's down the inside of my fingers, mostly at the joints. Between the ring and pinky is the worst hit area. As I said, when I was never getting a chance to recover, the skin would go beyond itchy and the blisters would break and finally the skin would peel off and it was red raw. Playing endlessly like that with sweat running into it was rotten. I was playing and singing and gritting my teeth all at the same time. I must be particularly susceptible to nickel as no one else seems to have this level of a problem.
