After a long day of constant jamming and aggressive fingerstyle playing, my fingertips get sensitive and hurt a little. Usually, we practice once a week so I can rest if my fingers hurt. But we're practicing again all day tomorrow, and I'd like my fingers to heal a bit. What's the best solution for sensitive fingertips? Cream? Also, I'm using my ring finger a lot more, and since it hasn't callused at all, there's a bubble thing on it. What's the best way to deal with them? Popping them? Or waiting for them to just die? Thanks.
