I was on a treadmill at the gym when, all of a sudden, I stopped hearing through my left ear. The only noise from it was loud, bad, tinnitus. I went to the docs a few days later (hey, I am a Glaswegian male and I could stll breathe) and was urgently referred to hospital. A bit of a shock, because I assumed it was ear wax. After an emergency set of tests, the doc there was puzzled. This was a Friday night. I was given an appointment for a consultant's clinic the following Monday (I might have been going deaf, but that was no reason to interrupt his golf). THing is, the whole thing cleared up on the Sunday night as quickly as it started. Did I feel a tube sitting through the tests on the Monday, saying "Actually, it's ok. Yes I hear that. Yes I hear that. And so on"
