Inner ear issue.

The other night my right ear and the right side of my neck and head were hurting a lot and out of nowhere. Also my right ear began to pulse? Rhythm? I don't know. But the pressure would flutter. Since then my right ear has had constant but slight "pressure" and I haven't been able to hear well out of it. However if I go chin to chest or chin to shoulder, the pressure relieves slightly and I can hear better and sharper. What's up?
