Years ago I worked in an office high on a hill by a window which allowed a very cold draft in on the left side of my head each winter. I worked there for 4 years and noticed left side temple, sinus sensitivity as a result. Since than I get serious sinus issues with post nasal drip at the slightest cold draft in that ear. The ear does not seem to be effected, but I have developed asthma and other complications which seem to reoccur each winter...My asthma is weather related not allergy related. I have had a post nasal drip for 3 months now, which I took one bout of antibiotics for..it is still here. I have used nasocort and advair for awhile...What is it that I have? I cannot understand what it is called since it always happens in the colder weather, and always seems to be triggered by a draft on the left side of my head...Summer is my only good time of year...Help?
