I seem to be able to taste food ok, but lost my sense of smell.
The problem started around 15 years ago, my sense of smell became distorted sporadically. For no reason, I'd smell something chemically on occasion. Then after a few months, could smell nothing. I thought it was because of the smog in the area we lived in. But moving has not helped.
I have a little trouble swallowing, and the upper nasal passages seem permanently congested. Not uncomfortable, but I wonder if it has a relationship to the problem.
Of 2 ear nose and throat idiots I consulted with, one said stop drinking coffee (give me a break), and the other said forget about it, it's permanent.
On very rare occasion, I can barely, faintly smell something, which gives hope that my sense of smell can be resurrected.
