<human>: For a while now I've had this kind of brain fog, where I find it hard to concentrate, my creativity and sense of humor has suffered, and I feel kind of out of my own head. I figured it would pass, but after I took a couple ibuprofen for a headache one day, my mind was clearer and worked faster than it has in a long time. 

I also get headaches behind my right eye, but I blame that on me not wearing glasses when I should and sitting too close to my monitor. But after this I'm actually worried I might have a tumor or something. I don't have health insurance at the time, and I work part time. My entire paycheck goes to rent. I can't afford any major medical problems.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I took ibuprofen and my mind worked better than it has in a long time. I don't have health insurance and I'm scared it might be serious. What should I do?
