Right hand locks up / overcontrol? Can’t perform even basic picking motions

Hi everyone,

I’m working on rebuilding my picking motion and struggling a lot with my right hand.

For context, I’ve been playing with a lot of tension in my picking hand for at least 10 years, and for the last 8 months I’ve been trying to relax and relearn the motion, but I feel like I’m not really able to make progress. At this point, I honestly feel quite desperate.

Also, I should mention that I’m left-handed for writing, but right-handed for many other things, and from the very beginning I learned guitar as a right-handed player.

I’ve also been trying to approach this from a USX perspective, but I’m not even able to properly perform the “primary motion” tests — my hand just feels like it locks up or blocks when I try.

Given that I’m left-handed for writing and the picking motion feels much more natural in my left hand, would it make sense to switch to playing left-handed, or is it better to keep working on the right hand despite the long history of tension?

Any advice would be really appreciated!

Left hand picking, it’s the first day that I try to pick with my left hand
