I have tonsillitis/ear infection and was prescribed amoxicillin.. my ear burst a couple of days ago, and ever since then I've had a lot of mucus in my lungs., I don't know if that has anything to do with it. But it's hard to cough it up, and when I do cough it up, it shows up clear. When I breathe, I hear a rattling sound. I don't have a fever anymore. I didn't know if I should go to the E.R. or wait over the weekend and go back to the doctor on Monday? I also have bad anxiety so I'm sure the freaking out is from that.
