Also he has a knot on his kneck under the skin by his right ear. He has be excessively biting at himself and they spots that he picks at turns red and the hair is gone. Also, he hardly come around unless u make him, he likes to stay hidden under the bed. I am really worried about him and just want some answers. PLEASE HELP

Answer
This sounds like he is having something affecting his skin.  The ear is skin also and that is why his ears are bothering him.  YOu should let your vet examine hime to see if he needs cortisone for his itching and specific treatment for an ear infection.
