I wish i could tell you- but i played this one piece at the beginning of last year for an assessment and it caused stabbing pain and inflammation in a tendon, and instead of it just healing in a couple weeks it affected every other tendon and it came up in my other hand somehow, so now certain pieces are hard to play and i tire out easily compared to a couple years ago when i had good stamina whilst playing. And i've been to physio and allat because it became unbearable and they literally said oh well- that was last year- and now they are blaming it on the fact that one of my fingers is weak (which in my opinion it isn't) even though it is in multiple fingers and they can't really do anything for me unless other symptoms start to come up more frequently than they have been.
