Off work

On Aug 10 I fell at work and hurt my left knee and my right side of my back, so I have been off work. Doing homework for my course and just resting my knee. I also go to therapy twice a week. So today I went to the Dr to find out when I could go back to work. Now my boss called yesterday and wants me to come back next Thursday, but the Dr said no two more weeks off. I know that my boss is not going to be happy,but I need to be able to bend and move just like I did before I fell. So now I will try to get more of my course done. I would like to be finished it by the end of Dec.But we will see.
