After just completing radiation and chemo this week my husband is still having such sensitivity to smell, mainly to people's breath. (This started about 3 weeks ago)Even after brushing my teeth and using mouth wash he still finds it almost nauseating. When the doctor was checking his mouth and neck he couldn't wait for her to back off since he finds it so offensive. He says our dogs breath isn't bad!! I wonder if it the spicy things like it salad dressing that linger, he can really detect garlic. Since it takes awhile for people to get back to eating spicy foods I wonder if there is some correlation??
