Ear Infection: This actually happened last year. My ears are usually kept clean, but for some reason the ear waxed collected to a point it was clogged and I couldn't clean it out. After trying some over the counter medications to help clean out my ears I went to the doctor. He took a look and came back with some of these that seemed a bit bigger and went much deeper:
When he stuck it in my left ear and dug around I literally was sweating. I had to keep myself from screaming and crying. When he finished the left ear he said "yup you have an ear infection, so I'm sure that doesn't help." The worst part...the right ear felt even worse than the left BEFORE he cleaned it.
