Hi hope someone can help, I more than often find it difficult to equalise my left ear, but sometimes i can do it without problems. I have been diving in the sea to 30m so I know I can do it and don't have any major disfunction with my ears. "Most of the time" when on dry land or indoors I cannot seem to equalise my left ear using the pinch and blow method. This often worries me, especially the night before a dive as i worry it will be a wasted journey. This evening for example, Im using an octovent balloon; sometimes I can hear my left ear cackle and pop, but another blow seconds later I cannot hear this crackling or popping, it seems odd. Is it possible while equalising on dry land, when the pressure is released (i.e I stop blowing/using a balloon) that the ear tube could remain in the open position, so that when the pinch blow is administered again (within seconds) it makes no discernible difference ?? Ive been practising equalising for the last hour and now my left ear feels slightly "dull" like its full up
