Why is my ear hot and red?

So just got home from the WordCampSF 2014 watch party all excited when I noticed the my right ear is all hot feeling a slightly red. So I Googled it up and here is what I found…

From http://www.livestrong.com/article/267469-what-are-the-causes-of-hot-and-red-ears says this that might be related to mine:

…You may also experience blushing in your ears, making them hot and red. Blushing often occurs in response to high emotions, such as anger or embarrassment.

What about excitement? I think thats what did it.

But on http://www.destroydiseases.com/Hot_Red_Ear.html it says

Hot red ear is becoming more and more common due to the higher ratios of Omega 6 fatty acids and not enough Omega 3’s. People are consuming more than 30 times or more of Omega 6’s.  &  Notice the bottom cartilage is not affected and not red at all. Only the top 2/3 of the ear is hot and red.

Interesting… has this happened to you? Let me know in the comments.
