Can anyone help or relate with this please - although I've had T. for over 8 years, I have recently been waking with a really severe humming, just I'm my left ear (my T.is bilateral). It gradually disappears during the day, so I go to bed with just (I say 'just', but you all know what I mean) my usual T. then every morning I'm waking with this dreadful hum again. Could it be positional or Cattarh? I really don't know & why only the left ear? It's really scar & every morning I wake up dreading it - of course you always wonder if today will be the day that it doesn't stop. Any ideas people? It's been happening every night for about the past 2 weeks.
