This post has me very worried. I hope that the ears were not wrapped so tight that the tips lost circulation and you have some dead tissue there. Not trying to scare you as I am not there but what you describe sounds bad. Ears do not have to be wrapped tight at all with the proper method. I would leave the ears down a bit and monitor it closely. If the tips have died you will need surgery and allot of after care. Hope I am wrong. How long were they wrapped and how long have they been discolored?
