Ok, so I got elbow pain from some bad technique and poly strings at high tensions. What's past is past. I'm a student though and my school work involves alot of work on my laptop, so I have to use the mouse alot. And this is worsening the problem. And I can't get the proper ergonomic position with my elbow to my side and at 90 degree angle because my armrest on my chair is lower than my desk. What to do?
