What's a good way to stretch your shoulder? - best ergonic mouse

I try to heal some of tendonitus to me always in the gym, weight lifting for a few months. It's really bad. So I made some adjustments Ergonic in my day to day, not to provoke on the shoulder, and some lines in the stretching machine in the gym. It seemed to help. What is the best way to stretch the shoulder in this state?
I take some pills the doctor gave me hope, help with inflammation.
