answer:Yes. I was sick for a short while, never had a fever that I noticed, but had drainage for a few days and thought I had a “cold”. Shortly (a couple of days maybe?) after it cleared up my ears plugged and wouldn’t clear no matter what I did. It just felt like the pressure and muted sounds like I was at the bottom of a pool. After a week I went to the doctor and they said I had a sinus infection, a round of antibiotics later and I was all set. It started to clear after a couple of days, so wasn’t immediate. There was no drainage that I remember after the initial sickness, and I felt pretty good other than the fact that I couldn’t hear and felt a little off balance. Nothing like what Jon is experiencing, just like I couldn’t judge my surroundings quite as well without my ears. There was nothing indicating that I had an infection other than the issue with my ears, so definitely not a fever or anything along those lines. I didn’t have any blood tests though, and I would think his body would be having some sort of immune response, but I don’t know enough about those tests to say. You mentioned antihistamines helped him some and those may have just relieved some of that pressure. So it seems like it may at least be a possibility. Maybe the office will call him in a antibiotic to the pharmacy? Maybe try some antihistamines in the meantime?
