I have noticed more headaches this year. They get MUCH better after a round of antibiotics. I was thinking they are recurring sinus infections but I am now wondering if antibiotics could be improving my headaches for other reasons. The pattern is that my headaches get really bad every few months with a lot of cheek and forhead pain. Migraine meds don't touch these headaches. After 2-3 days of antibiotic they are much much better. Dawned on me today there might be a link other than sinus infection. Any thoughts?
