Recently...like this past couple of weeks, I've been getting really bad headaches about every other day or so. I've taken Tylenol each time and it goes away. But then 2 days later I get another one. I could just be laying in bed and all of a sudden get one. I don't really listen to music ultra loud, or do much that would make me have a headache. So what's wrong with me? Do you think this might be serious and I should go see a doctor?
