As you can see my grip is....WACK
I have constant hand/wrist pain/soreness and I think its partly due to my grip and tilt i do with said grip,
The mouse in the pics is a Hyper-x haste 2 wireless if that helps anyone out ,
I have tried TONS of different mice but have yet to find one that is 'comfortable' enough to let me play for long [ish] periods without pain or some sort of soreness
Measurements are in the pics as well
realllly need some suggestions because I have no clue what to try anymore
