I started with headaches in back of head then I lost my smell and taste. After continuous antibiotics, ENT discovered my Sephnoid sinus was very infected. After a 2 1/2 hour surgery, I am on a rinse 3 times a day. I have not gotten my smell or taste back. ENT said it may not come back or could take a year or more. I can taste salty, hot, bitter and sweet but no flavor. It’s hard to describe. My ENT said it best. I can take a bite of chocolate pie. I know it’s sweet, but I don’t know it’s chocolate if I can’t see it. Wish I was more helpful.
