This last week I've noticed a swelling in the upper cartilage of one ear. It's about the size of a moderate mozzie bite and possibly fluid-filled but without any pain or itch, actually no abnormal sensation other than the swelling. I haven't taken a hit to the ear or do anything such as a contact sport. I wear glasses with my helmet and I'm wondering could the pressure from the helmet cause such swelling? Otherwise could such a thing happen when my ears get folded just as I pull the helmet on? (My ears aren't folded when the helmet is finally on.) I've got a doctors appointment in a few days so I am getting it checked out. Just wondering if anyone has heard of such a condition caused by a helmet.
