I sure know what you are going through i could not raise my left arm without having severe pain I thought somehow that I had a torn muscle in the shoulder I had a good O.T who was able to get me through it she put a muscle cream called Biofreeze on the shoulder along with a warm towel before every therapy session with a lot of stretching exercises I was finally able to get through it for pain I used tylenol with codeine since you use tylenol you might also see if you could use Norco it is a little stronger just
