This etude draws you to intense practice to the point of obsession, doesn't it

How long have you been working on this piece?
You may have small hands.
You may be playing with the wrong motion.
Your may be holding your wrist too low or high.
Your muscles may be too tense.
I wouldn't worry about it if the pain stops after some time.
Wide ascending arpeggios should be more difficult than the others for you, right?
Someone also experienced this?. thanks!!
Yes. Then I switched my motion to displacing my hand, rather than stretching it, and started practicing in 15-20 minute sections with another 15-20 minutes of practicing Revolutionary Etude inbetween.
