I went to a rock weekend. It damaged my ears. I now have pressure behind both ears and it's horrible. Also sounds are muffled. Wish I'd never been. It's appalling that it's allowed.

I wrote about it here. It barely got read, so perhaps I should delete and republish next month. https://medium.com/writers-blokke/my-first-last-rock-weekend-how-a-writing-assignment-led-to-ear-damage-7a32adb2bfda
