At work today I was explaining a math problem to one of my students, when suddenly it felt like someone stabbed me in the top of the head. I had to sit down, and even though I don’t generally take asprin or anything like that, I took a tylenol from one of my students. The pain went away for about half an hour, and then returned for a few minutes. Since then i have had a mild throbbing in the middle/top of my head. I’m scared. If it’s not gone by morning I’m going to have to go to the hospital. Shitty.
