I recently got my tonsils removed after a series of throat and ear infections, caused by glandular fever, over a few years. I have had my ears pierced for around 10 years now (I'm 20 years old) and despite long periods of not wearing earrings the holes have never closed up. Over the few weeks I was recovering from my tonsillectomy the holes in my ears have closed up completely, even though I was wearing earrings in the lead up to my operation. I just wondered if this was normal, and why this would be? I wondered if it was to try and fight infection.
