I am a 24 year old woman. I work at a restaurant on a college campus. I started working there last August. One night, about a month after I started working there, I started to get terrible stomach pains and nausea. It didn't go any farther than that, so I went home, and I ended up being fine. About two weeks later (again at night) it happened again. This time I vomited, and I ended up leaving work early. It happened two more times, and I didn't vomit at work, but once I got home, I did. I believe the last time it happened was in November. All through the spring semester, I was fine. I didn't work in the summer. I just returned to work a week ago, and this past Friday night, it happened again.
This time was worse than ever before. I felt sick/stomach pain for about an hour before I finally vomited. Once I did vomit, I felt fine for about thirty minutes and was able to go back to my work. But after that, I ended up having to run back to the bathroom. I was sitting on the floor next to the toilet, and every time I stood up, I felt dizzy. I was sweating, and my manager said she thought I had a fever, though we didn't have a thermometer to take my temperature. As soon as I got out of the building, I felt 100 times better, but I still felt slightly nauseous for the next two days.
It only happens at night (always around 8-9pm), and it only happens at work. So far, it has only happened in the late summer/early fall. The building is very old and connects to the dining hall, the student union, a dormitory, a game room, the post office...it's a huge plaza-type thing that all shares a single ventilation system, which is why I think it could be mold or some other allergen.
It's not connected with what I'm eating or drinking; I've changed that in an effort to stop it. It also doesn't seem to be connected to how hard I'm working. It has happened on a 12 hour shift, but it has also happened on a 3 hour shift. But one of my coworkers (who is a senior in nursing school) says that might not make any difference because there is one other thing - I have "chronic mono." I know there's a lot of controversy over whether or not that exists, but I went to two different doctors who told me the same thing. Regardless, I have a condition that causes phases where I'm tired nearly all the time, so I could easily get exhausted on a three-hour shift, and my co-worker thinks that's exactly what's happening.
I can't go to the doctor for at least another month because I don't have insurance, and I won't be able to afford it until then. Any thoughts until then?
