My six year old son has been constantly itching his ears - not the inner ear (ear hole), but the outside of his ear. It is very distracting in his day, and he seems to not even notice when he is doing it - can't control it. He used to do this when he was a toddler, but it just went away. We figured it was something equivalent to thumb sucking - just something to grow out of.

Now it seems to be accompanied by spaciness and distance.

Does anyone have experience with this?
