My Ears have been blocked since I got off the plane yesterday - over 24 hours now

I have a cold, and perhaps an ear infection - I cant get to the Dr until Tues. Any idea's on how to 'Pop' them naturally?

I've tried flushing the gunk out with a bit of warm water - no improvement, Have tried blowing etc, and some nasal spray etc

I am going mad, its so annoying - and I am sick of saying 'WHAT' to my DH cos I cant hear

Help
