What does it mean when only my right ear is really hot and very red. (left ear is normal/cool). Freaking me out!
Yeah, my right ear does that when my jaw (TMJ) is bother me or if my ear is infected. Otherwise it could just be a fluke.
Maybe it is from you laying on it or having something up against it. I wouldn't be that worried though, it's probably nothing major. If your worried you can get it checked.
Did you have pierced ears? Is there swelling? Wear cheap ear-rings lately? If there's no pain or swelling - It should be fine - otherwise, you may have an infection brewing.
my ears do that too and so far I have found nothing wrong with them. but i wouldnt be too worried but if you are really like freaking out about it you should go see a doctor if you are that nervous. but it is probobly nothing to be alarmed about.
