I have the same problem. It's only been a week now. Left ear, top of the helix, no visible inflammation or anything, and I doesn't feel a thing if I don't touch it exactly at the right place. It feels like I broke the cartilage
in my ear. It doesn't bother me much but when I hit the right spot, it hurts like hell. I would really appreciate knowing what it is and how can I get rid of it.
