About two years ago, I had several things going on at once that required a triple course of antibiotics. One of them was an upper respiratory infection. After this, I was stuck with an unpleasant, musty smell in my nose. Sometimes it changes character to a strong yeast smell, or something like cheese. This has continued on and off for the entire two years. Then there was this odor that smelled like chemicals or something. Yesterday afternoon, I started smelling that odor again. It reminded me of hot metal, or chemicals for lack of a better description. The closest I can compare it to is maybe bleach, or nail polish remover. Accompanying this, are extremely hot and inflamed sinuses, and no mucous production. It is driving me crazy! The last time I experienced this, my doctor examined me, and said that my sinuses were inflamed, and prescribed steroid nose drops which only over time caused a bleeding sore inside my nose. So I stopped the drops. I have been trying warm Neti pot rinses with a bit of salt and baking soda, Xylitol nasal spray, and regular saline spray. Nothing seems to relieve that awful smell and the sensation of hot dryness. I even read somewhere that putting a drop of baby shampoo in the Neti pot might help in case it's a biofilm that has taken over my sinuses. So far nothing helps, and the smell is maddening I can't enjoy my food and can hardly smell normal things because this smell is so potent. And my eyes are drier than usual as well. Does anyone else experience this? Any suggestions? I am desperate!
