Several weeks ago I had a sinus infection. Prior to the infection I had an excellent ability to smell & taste. After the infection passed, this ability was greatly altered. Now, EVERYTHING smells and tastes exactly the same... kind of like roasted garlic. I can distinguish things like vinegar and salt however. I thought that perhaps these senses would return to a more normal state given a bit of time, but thus far (6 weeks) no improvement. Is there anything I can take to restore normal function?
