blister from popping?
I've been practicing slap n' pop for a few days, there wasn't really a problem.. until today. i tried playing can't stop by rhcp, practiced it for basically the whole day and noticed my right index finger forming a hump. i didn't think much of it and continued playing.
it's now late at night and the hump turned into a small blister. I'm jst wondering if this is normal and if i should be concerned? it doesn't really hurt, jst a hassle to play with.
