Two years ago, at the beginning of school, I went in for 1 day, and was then gone for the entire week due to a really bad inner ear infection.
I was drowsey and delusional. Then my brother had an inner ear infection just after I got it.
His lasted for two weeks though.
The year after, which is last year now, I started school went in for 1 day and had to leave halfway through due to really bad sickness. The week after, I believe, I was off for another week with another ear infection.
Most likely due to the fact that about a week earlier, I was around my cousins house for the weekend, and they had one of those family size swimming pools up. The water probably wasn't as clean as it could've been.
