Suggest Treatment For Clogged And Painful Ear

My right ear was clogged last night and was in a lot of pain. I tried hydrogen peroxide, ear drops, and water, and it made the pain a little worse. I somehow managed to go to sleep and woke up without pain, but my ear is still a little clogged, and people sound like robots. My voice sounds okay, but people and any other sound sounds like robots. Please help! At least tell me my hearing might go back to normal soon...
