Hey Anthoroszko! The pinky is important when playing guitar. Especially being able to play chords. Since you have a unique physical situation, I would suggest working with your physical therapist on helping your pinky regain mobility. Otherwise, I will suggest booking a 1on1 lesson with one of our instructors so they can take a personalized look at what's going on, and give you ways to move forward.
