I am getting frequent headaches at different locations on different days, like forehead, top of head, side of head, facial pressure, behind eyes. It usually stays for a week and goes away and comes back again. There is no sinus discharge and my nose is clear. Doctor told me it's chronic sinusitis and prescribed antibiotics with other medications. Took it for 3 weeks and it looked better for 2 weeks. On 3rd week headache comes again although I was on medication and doctor asked me to change the antibiotics . The headache is very irritating and dizzy feeling with some light ear pain once a while. Not sure how to overcome this. Any help would be appreciated
