I need some medical answers please!?

okay my right ear is really having some problems, im 14 just to let you know. My ear has this feeling like when you get water in it or when you change altitude in the mts but it wont go away! i had strep throat last week and it kindof started then, like when i was congested it would do this, but would go away when my nose cleared. But this is just staying there! We put some hydrogen peroxide in there and it bubbled for a while like it was dissolving something and it eventually stopped, i emptied it out and it was still like this! It actually got worse! i stuck a q-tip into my ear all the way to my eardrum and theres nothing there! Its really aggravating and we tried everything so far, i took a Claritan (maybe a side effect of it?). And that didnt help either! and how yawning and swallowing usually helps but it seems that nothing works! anyone know what the deal is?
