Shoulder pain

I know we have had the discussions about Frozen shoulder before, but I was never sure if that was what my problem was. I also thought it has been awhile and some of the new people might want to read about it. Last week, I was having spasms in my upper back, not continuous, but irritating. I thought it was because I am doing more things around the house with the remodeling. Then yesterday, for no reason I could think of, I was grocery shopping, I had a terrible pain in my right shoulder. It was so bad, it hurt to breathe. Today the pain is much worse in my shoulder, but I am also still having the spasms in my upper back and under my arm when I take a deep breathe. I can move it any way, without pain, though. The pain just "wears me out"! It’s like having a bad toothache and thinking it would feel much better if you could just knock the tooth out. 😮 If it is "frozen shoulder" though, am I going to have to get through Christmas with it? I could not get into see my doctor until Monday, and I am so hoping it will be better before then. Tylenol doesn’t help at all, Ibuprofen helps, but sometimes hurts my stomach, I am saving it for when I need to sleep.
