My new party trick....not.

I've been having problems with my ears for the past few weeks. Best way to describe it, is an uncomfortable feeling of pressure. After seeing the doc twice , I've now got to do this.  Wait for it.....blow a balloon up with my nose, yes , you read it correctly.  Blow it up to the size of a grapefruit! If only! I cant do it.
 I try three times a day and cant get it to expand. Although my trying is somehow helping my ears and equalising the air pressure in my ears. They are starting to feel better. 
Had to send four serial coughers home today and it's still been a hard day. So hard I've just scoffed two chocolate bars! Making bear hats tomorrow,  grrrrrrr.
