Well, it´s simple, i play normally osu, and when i have dinner and take a shower like usual, when i come back i can´t play anything because for some reason i don´t know, i can only play really easy and slow maps and after two or three songs my right wrist, arm and shoulder start to hurt a lot and i have to stop, it happens everyday, lke a ritual, i don´t know what it could be because i hold my pen in the same way before and after (https://imgur-archive.ppy.sh/cfohGoC.jpg) And i don´t even know if that is a good pen grip anyways, but if doesn´t matter if i try hours to warm up and try to play normally again, it just doesn´t happen and always i have to turn off osu because there is no point of playing worse than usual and even hurting myself while doing that.
