I have tubes in my ears and something is wrong! HELP ASAP!?

Um yes. I'm Amanda. When I was 17 I got tubes put in my ears to help me from haven ear affections and hearing loss..Well now I'm 18 and I have no insurance to go seek help. Well last-night I woke up around 2am and realized my left ear wasn't right..It sounds like there is a big air bubble in it I can hear EVERYTHING much louder then the other ear...It even hurts. So I would push on it and it will go away but 2 seconds later is back is worse..I can't sleep with it and it's so annoying that it's starting to frustrate me . It's so bad I can hear cars...even if I swallow I can hear it. I don't know what to do. Is the tubes doing this...It won't go away..there is no WAY it's an ear infection.
