Hi there, since I can't seem to know anyone that I can seek advice on, as well as searching the internet, I decided to seek from you guys, my fellow graal players

. I am actually 20 now, and I wanted to learn how to play since when I was at a young age, and now that I got the chance to learn. I have ONE major question and concern, my left hand gets hurt after practicing for a few minutes. Is this a major issue? What if I have had an injury from when I was younger? am I still able to get better playing the piano(its a keyboard actually)? Or is it normal for beginners? Thank you in advance to anyone who can give me some advice
