Some days, when I play, my fingers refuse to move and hand feels numb What do I do?
I am not surprised this happened since you've been playing a lot of repertoire that IMO requires much more experience than what you have. What worries me is that your teacher allowed this.If indeed you do have nerve damage from playing, even after you take the required rest you will continue to have problems unless you retrain the way you play. Which means going back to basics.
The only difficult ones I have worked on are moonlight 3rd (which I have basically dropped and play once every week or so) and the first movement of waldstein (I practice this one very, very slowly...)as of now... And op.2 n°1 1st movement, which I'm performing next Saturday, if you count that.Regarding the second part of your post,1. How can you tell if you have nerve damage(other than numbness and refusal to move)2.how long is the "required rest"?3.should I go back and reforge my technique from scratch or should I just work of easier pieces? My teacher wants me to work on bwv. 999 prelude in c minor and other pieces from that level.
Stop playing immediately.
Do I only stop playing when I feel it or do I stop playing all togetherness? I have a recital in a week.
I am not a doctor. You need one.You have a recital in a week? The problems started recently?Sounds like you may have practiced too much in a way that is not good. I am not the one to tell you what to do. If indeed you do have nerve damage and if it is from playing, it would be best to not play. Then again I you have to, at least stop when it doesn't feel right.
