What is wrong with me?

okay last week i was diagnosed with an ear infection. They put me on amoxicillen aand gave me ear drops. They said i have blisters in my ear. It was my right ear. And the whole right side of my head felt a lot of pressure. They said that was from my ear being so clogged up. Well its been a week, and now my ear is still a little clogged and the pressure on my head is still there a bit and that side of my neck and shoulders are sore. Idk if its the way im sleeping or what. They said they found blisters in eardrums. Its been a week and this hasnt gone away, only a little. I had to go back because the first antibiotics they put me on were not working. What could be wrong with me?
