Suggest Treatment For Dry And Scaly Bump On Side Of Neck

I have a large spot on the side of my neck that is really dry and bumpy and scaly. It has since proceeded to ooze this weird liquid and the skin is peeling away. The skin peeling has gotten so bad that the spot is dark and indented. The same thing has also been happening to the end tips of my ears. I went to the hospital and they gave me various medicines for allergic reactions. It started out of nowhere in August.
