Hey. I've been playing osu!mania for almost 3 years and i stopped improving after 5.1k pp. I took a break from playing for a month, then I literally had to learn to play again. I couldn't even pass 5* on S.. My left arm hurt and i don't know why. I can't even handle straight spam for more than 10 sec. arm started shaking everytime i playing and it's really hard for me to improve. I feel really bad that I can't play like I used to, I'm losing motivation to play the game I used to enjoy.. maybe there are some ways to recovery stamina?
