I haven’t been feeling myself lately (for about 3 weeks). I’ve been having mild headaches with slight lightheadedness or swimmyheadedness. My symptoms tend to be worse when I am in an area with many people and a lot of background noise. It is as if I lose my concentration and can’t focus well with extra noise. For example: I am in PT school and during group work, I have trouble concentrating on when my group is saying when everyone else in the room is talking as well. It is really hard to explain exactly how I feel, but I just know that I don’t feel like myself.
