I got an injection in December. The pain was gone for a few months.The pain is back and I need another injection. I have come to realize it is from using the mouse at work all day. My concern is that I love my job and boss and don't want to cause any trouble for them or me. If the problem goes away after the shot-no worries, but if I end up needing surgery, can I, at that time,mention that I believe it's from repetitive use at work. I'm just not sure what to do and what exactly workers comp means to my employer. I am NOT trying to have a "case" or get money but I am concerned that it's my dominant hand and if I ended up with surgery & it didn't work....then what? I need advice!
