Hi everyone. I have a question, maybe someone has experienced this. A week ago I got sick (runny nose, nasal congestion) and stopped being able to smell and taste food. Now it seems to have passed, but there's constantly the same smell in my nose (cloyingly sweet), no matter where I am, indoors or outdoors. How can I get rid of it? It makes me feel constantly nauseous because of it.
