Which hand do you use to operate your 'mouse' ?.
I had pain in left arm/wrist after a lot of use whilst researching recently.

Could be a form of repetitious movement injury....Carple Tunnel
There is a large nerve running through your elbow..Ulna. This is easily damaged and used to be called Tennis Elbow....
Try Googling 'Ulna' .
