I have the very same problem, it kills in the morning or even when i wake up half way through the night and i have to turn over, then that one will hurt! My pillows are soft too, affraid i dont know what causes it but at least your not the only one.
The same thing happens to me every once in awhile. It really hurts. Sometimes for hours after I get up. I always thought I bent my ear some how when I rolled over and then slept on it. That's the only reason I could figure out that it would hurt.
I too have the same problem and have realized that I actually do bend my ear over. It only happens on the right ear, not when I sleep on the left side. I have no explanation for why it happens but it sure does hurt!
