I have constant pain in my shoulder, its not sharp, more of a dull yet agitating pain. what could this be? - shoulder pain more condition_sympt oms

I have a lot of discomfort, if I sleep for an pilow sometimes help. When I awoke, the pain is gone, but after several hours, initially, was just above my shoulder, but is now on my right shoulder blade. I think it is, and massage helps a little, but do not have them. I tried ice, a hot towel and Epsom salts, hot shower and stretching.
