Some questions about Chopin's Etude op. 25 no. 5

[erikd2y]

I'm currently learning Chopin's "Wrong Note" Etude and I'm halfway through the scherzando part, but I noticed that my left hand starts to hurt after I play it for some minutes and I really want to know what I'm doing wrong. I'm not turning my wrist for the arpeggios because my hand is big enough, but maybe that's the problem. Or should I move on to an easier etude? Op. 10 no. 12 is easy for me, so I think I should be good enough for this etude.
I don't have a teacher atm, that's why I'm asking you guys.

Thank you!

P.S. sorry if there are any mistakes, english isn't my native language

Where do you feel pain?
Based on what you described, it is possible that you're putting a bit too much tension on your left wrist when you don't turn it while rolling the arpeggios. Try doing it even if you have big hands, it's still good to keep your hand light, even if it means moving it around a bit more.

It's most painful in the back, maybe I'm just not used to these large arpeggios. But thank you for your advice, I will try using the wrist more and not putting so much tension on it, I was just worried I was doing it completely wrong because I never felt this before and my last teacher said your hands can get injured from these kinds of things.
