I recently started playing the ukulele, but after some time practicing, my left hand starts to hurt from rubbing against the nut. It only starts to hurt after playing for some time, but it still is keeping me from playing as much as I would like to.
Me, playing a G7 chord. When I switch chord, my hand is going to brush against the edge of the nut.
When I play a D or an Eb6 chord, my hand is even directly against the (pointy-ish) edge of the nut, and if my hand is already irritated from before it hurts a bit too.
What can I do to avoid this pain? Am I holding my left hand wrong? Should I file down the edge of the nut (or have a professional file it down for me)?
