Just purchased two bottle babies and noticed today that one has a bump near middle of her ear, underside, and hair loss on the opposite side of same ear. I don't suspect an abscess or infection because it doesn't seem painful, but wondering if she possibly tore her ear prior to coming home with us. Would a torn ear "heal" like a bump? Or do you think i should treat with ointment for possible bacterial infection or sore? Thanks! Btw, I hope I'm posting this right, haven't been on in a while.
