It can be be aggravated by repeated use, even if it is not anything very physical. I don't know if it can be caused by this. I tore mine (not too badly) several years ago in my right shoulder. Believe it or not, grading tests can aggravate it. At the end of every semester when I have a lot of exams to grade I will get a bad flare up. Just from grade page, flip, grade page, flip, etc. I mean, what does a couple pieces of paper weigh? Next to nothing, it is just the constant repeated motion I guess. At the end of grading those exams I'm in pain for about 2 weeks.
