I had the same occurrence with breathing and allergies. Never was allergic to anything except dust and all of a sudden BANG I'm allergic to everything except food! Had infection also and went on a bunch of anti meds. Took 2 months to get it under control and now am back to normal. Off all drugs but am wondering what the spring season will bring and if this is just temporary reprieve or is there another round coming. Good luck with your endeavor and I wish you relief!
