Strange incident with ear. Don't know what to think of it.

Definitely sounds like a reverse block. I had the same thing happen a few years ago when I was teaching a course. Everything was fine the whole dive then on the way up bam! It sucked, had to take two weeks out of the water. It was pretty sore for maybe two days then it stopped bothering me so much. That stinks but there was nothing you could have done about it
