Two years ago, I spent nine months with sinus infections. I had one after another, and if I didn’t go to the doctor and get antibiotics, I got so sick that I would throw up. None of the doctors I saw could figure out why all of a sudden I was so prone to sinus infections. I saw an ear, nose and throat doctor and an infectious diseases doctor, as well as seeing almost every doctor and nurse practitioner at my GP’s practice. I had every test you can imagine. And no one could figure out what the problem was.
Finally, when I was on one of my (by now) bi-weekly visits to my GP to get a prescription for antibiotics to fight the most recent infection, the nurse practitioner said, “Why don’t we check your Vitamin D level.” Sure enough, I was extremely deficient. The standard range is 32-100 ng/mL. Mine was 20. I was put on prescription Vitamin D and voila! No more sinus infections.
