I have finally gotten serious about playing guitar and because of my age, I am hitting a real problem, I have pretty severe arthritis from my wrists down and it effects my playing. The C chord kills me!

But I'm not going to quit! I have an Epiphone Les Paul Standard, Ibanez Artcore AF55, and a Fender Squier Classic Vibe. For some reason the Les Paul plays the easiest for my hands and fingers, (least amount of pain during and after), but the other two are acceptable.

I would really appreciate inputs on upgrades for the necks, nut replacements/alterations, and perhaps the strings, for playability with regards to my arthritis. Thanks!
