I had a blister on my index and middle fingers on my right hand. Last night at our show, the blister on the middle finger tore off and took some more skin with it. I didnt realize it till after the song. So i was playing on my last layer or skin. Its pretty gross. It hurt really bad once i got home and sat down finally. At the show it just kinda stung. But now....oh man. At least the gig went well.
