You are going along perfectly happily and then, suddenly, you’re in acute pain - it stops you in your tracks - you can hardly speak!
Over the next couple of weeks, the pain gradually subsides, although a couple of times you do something silly and it catches you again – agony! This happens once or maybe twice a year, without warning, but you never see a doctor or seek any medical advice or treatment. Why? Because you’ve accidentally just bitten your tongue while talking or eating. It happens to almost everybody at some time or other.
