Recuperating (sort of) from a really annoying tendon rupture in my guitar fretting hand pinky, I've been warned against vibration as it disrupts the healing process.
I don't mind doing the dishes (with a rubber glove over the splint). It's the least I can do in exchange for the wonderful meals Mrs. Teflon makes. Damn sight healthier too, I was a ticking time bomb as a bachelor.
Back to my wounded finger, Doc finally cleared me for all activities this week, including things that shake and vibrate. I'll let her know she doesn't need to mow the lawn anymore - probably in September or October.
