My sense of smell and taste diminished. I also smell things that are not there like smoke (and it burns my nostrils). Its about a year now. Normal CT and MRI. ENT says there is nothing. I will NOT do a ingest by mouth any cleanse as per my internist. Does anyone suggest a natural remedy?. I heard 50mg of Zinc may help. I cant taste if foods are bad so if I get sick, I know I missed it. I cant taste my delicious meals anymore. Its as though I have a congested cold but Im clear. HELP
