So this is a weird predicament I have. When warming up on DM I'll notice after about 10 minutes my right hand (mouse hand) will start to get sore/cramp up. This doesn't happen in regular comp or unrated at all, only deathmatch. Does anyone have any advice on the matter? Everyone I've talked to has just said take a break, but the thing is it happens after playing for only 10 minutes. Thanks for any advice and help!
