Hubby has a telecaster and just acquired a 2016 Les Paul. He says it helps keep his hands moving from the arthritis.
I have been fearful of losing the use of my hands. I have RA and my g-mom did, too. Never thought about guitar for that. She played the organ until in her late 60’s I think. Probably not as much movement needed. I think arthritis is stress related. Tonight trying Benedryl for the first time.
