Throat and Ear problems..driving me crazy

For the past couple months or so I have been dealing with some terrible throat and ear problems. The left side of my throat feels like it's blocked up. When I swallow it seems like everything is going down the right side of my throat. This is also affecting my left ear which feels really blocked. The only thing I found to work is holding my nose and blowing really hard. This opens my ear up and also opens my throat up but then a couple seconds later they both block up again. If anyone has any advice for me I would greatly appreciate it, it's driving me insane.
