Hi! Last night I was playing osu! I started to notice a pain in my right hand, it feels almost as the muscles are tightening very hard, I swiftly stopped playing for the night as i have hurt myself playing mania and did not want a repeat of anything too serious. I woke up this morning and hopped on Osu! I felt fine for 3 songs and I decided to play Overwatch with my friend, afterwards i hop on Osu! and within minutes the same portion of my hand from last night was in searing pain, could someone help explain what would cause this and how i could possible help the pain with certain stretches? Also just an extra bit of info, I brought my computer over to my friends house, so i am sitting on a different desk at a slightly higher angle, I would assume this causes the problem but it has never shown up before (Even after marathoning for hours) Thanks again! Here is a pic for reference so you know what i mean http://imgur.com/a/RJXtw Thanks Guys!
