I have a unique and disturbing inquiry about myself. I get colds extremely easily; going outside without a hat, or my neck being exposed to a breeze, summer or winter. I ve been to many doctors about it; gp, eyes nose throat, naturalpaths, etc. I can be outside for under a 30 seconds, no exaggeration, and start to sniffle within the hr. i m very sensitive of to cold/breeze while everyone else around me thinks i m crazy for wearing a hood when it s 9 degrees Celcius, for instance. One doctor has told me that my left side of my sinus swells easily. Whenever my immune system, or my respiratory system, has been checked out, everything has come back as normal. I generally take zinc or oil of oregano at the onset of the cold, and it usually knocks it right out. Reactive rhinitis? perennial allergy? Something else?
