I am a normal 33 yr old female and I have been documenting for several months that a week before my period, I get a sinus infection consistently. My doctor is brushing me off saying its PMS, however I am not satisfied with that. I go to my regular physician and he loads me up with antibiotics which are not working anymore. Had anyone had any other issues like this? I am also on orthotrycyclin low (birth control pills) I am at my wits end with this as its really effecting my quality of life dealing with a sinus infection 2 weeks out of the month. Any help greatly appreciated Thanks Lori
