I'm relatively new to osu. I've been playing for a few months and have been focusing on beating maps that I can barely keep up with, so I can consistently challenge myself and get better. Today I was playing a map (some 5* 4-6 minute Camellia song) and at some point late in the map, my stamina started running low and my hand just started gripping the mouse weird. I play at a pretty high sensitivity (relative to my friends, at least) so I usually move my mouse with mostly my fingers. While the song was getting more intense and I was getting more tired, I was struggling to keep a consistent grip on the mouse. When I beat the map I let go of the mouse, but when I put my hand back on it it felt anything but natural. I decided that it was whatever and kept playing, but I have stopped because I can't get my hand in a comfortable position. Please help. I hope this isn't a big issue and can be fixed relatively quickly
