Ears turn red and burn with no apparent cause

my son has the same problem.  we were coming home today and it happened in the car.  the other night it happened after he went to bed.  it is very uncomfortable and happens for no apparent reason.  i can find no triger.

There are a number of reasons for blushing or flushing of the skin.  Examination by a dosctor is the only way to tell which reason it may be.  It could be normal.  It could be a social anxiety with an unrecognizable trigger.  It could the very beginning of Rosacea.  It could be a thyroid problem.  It could be a symtpom of some disease.  Undoubtedly a doctor could come up with more things it could be.  They are the only ones who can test and really see what is causing it.

That happens to me too all the time. I'm in middle school and usually around the end of the day (8th hour) my ears get hot and turn red. It's super embarrassing and I can't control it! I asked my brother what was wrong and he didn't exactly know but he said just don't put ice on it or something cause that will just make it even more hot. I have learned NOT to think about it or it won't go away. I still don't think it's because of my emotions or anything though. It happens randomly. Sorry, I don't know what causes it or how to fix it. But I wish you the best of luck!!!!
