I was diagnosed several years ago with an IGA deficiency. As a result, I have reoccuring sinus infections on a monthly basis. I am never off some form of medication longer than two weeks. Currently, I have had ear pain for two weeks and it has gotten to the point that my doctor will ask me what I want him to prescribe. I have taken every medication available and my body has now built up a tolerance so nothing works anymore. If any of you have experienced this problem, please let me know what you have done that works. I am not opposed to natural, organic or herbal meds if they will bring me some relief. My primary care physician, ENT and allergist have all made the same conclusion. IGA defiency. Had the surgery, didn't work.
