Is it possible to get herpes simplex on the outer ear (it formed on the antihelix of the outer ear). It appeared at the same time as a cold sore on the lip immediately following a few days of a fever. The blisters looked the same initially but the one on the ear was bigger, more painful and caused mild redness and swelling. By day 3 it had stopped spreading and the blisters are starting to crust over, redness is subsiding as is the swelling. Just curious what it could be. There isn t any definitive information online about cold sores in the ear so I am curious as to what it could be.
