I'm starting to get a pinky joint issue on my fretting hand. I've been practicing a song a lot that is in the key of A and has a lot of the xx2225 position. The chord is really x0xx25 in the notation so I could actually make it easier on myself but habit makes me do the full chord. Anyway it hurts when I switch to something like 2xx230 (pinky on the b string) and other positions now sometimes. I'm thinking taking a break from the key of A might be a good idea or at least this song (which is a fun one to learn though.)
I have to admit I've been practicing this song for at least 2 hours a night since 3/3/18.
I could load up on Advil/Motrin too,
