While snorkeling in Belize I got water in my ears. It took a few days to clear, and I knew that was a signal that something was not right. I also continued to have pressure in my left ear for a week afterwards. When I went to the doctor after returning home, I was told I had wax buildup that had to be removed. It is somewhat ironic that I complained about water in my ears and the first thing they do is flood my ears with water to remove the excess wax. When I saw the solid hunks of wax that came out of both ears I asked the nurse to confirm that it was indeed wax and not a jungle creature that crawled into my ears.
