I wonder if anybody has advice for playing slap...lately I'm experiencing a lot of pain in my right hand. I can't really practice or do gigs on DB. I used to feel slapping in my bicep (the good tired muscle feeling) but these days it feels like the entire weight of the string is being pulled by the inside part of my palm, between the thumb and pointer finger. Everything else is fine. Arco, jazz pizz, bass guitar & regular guitar (with and without pick) are all no problem. I'm playing Evah Pirazzi slap strings which seem pretty low tension to me. It's getting really frustrating, I've been slapping for about 8 months and have been making great progress. It's not like I'm overdoing the practice either. Also forgot to add I'm only 34.
