What Causes Upper Right Back Pain?

i have moderate pain in my right shoulder/neck/upper back area. It seems to be worse at night and in the morning upon waking, it feels better if I apply pressure to the area which makes me think it s muscular but it has been going on for months now with no improvement. I ve used muscle creams, Aleve and gotten massaged but it s still there. Related seems to be a pain in my ear, which sounds strange but it s been going on the same length of time although it s not constant it s more infrequent and a sharper pain. I ve been to my doctor but he did not diagnose any problem. Said to take muscle relaxant and anti inflammatory.
