Very suddenly today the lower helix of my ear began to hurt and feel hot to the touch. I also noticed some hard bumps. I felt my other ear to compare and felt some bumps too, which I assume is the cartilage, however the bumps on the hot ear are much more prominent and almost feel sharp. I took some pictures as I couldn t get a look in the mirror and noticed a white, blotchy, patch where the pain is. What is this?
