I must have had 5 or 6 of these complaints so far this year. "I hit my ear on a pole on the playground" or "I hit my ear on the door."
Do you mean you hit your head?
"No it's just my ear." Usually points to indicate the top of the pinna, where cartilage piercings would be. (Thankfully mine are all too young for that.) Never any swelling, discoloration, they let me touch and manipulate the area without saying "ow."
It's just so weird! Has anyone else had that? What do you do for it?
