I've had this my whole adult life. Can't count how many sinus x rays I've had, bouts of bronchitis, and pneumonia (once). I never get a regular cold. It either stays at an annoying allergy level, or I get really sick. I have been much better since 1) I left Arizona, 2) since I started using the saline sinus rinse (i use the Neil Med one), and 3) exercising outside in the winter.
I also know that if I pass a certain point, it will always go into my sinuses and/or chest.
