I've been smelling something strange in my nose all the time and it doesn't go off. This smell was there years ago but it seldom comes and goes off soon. But now, it doesn't go off. I don't smell it when I'm breathing but when I breathe in/out hard or press my nose and breathe, the smell will be stronger! Help please.
Have you recently ingested any zinc cold remedies? These products can cause olfactory nerve damage which results in odd smells/tastes and even a complete loss thereof. I have olfactory nerve damage from a zinc cold remedy (cough lozenges) and I smell sulphur or burnt hair all the time. When the damage first occured I smelled ammonia very strongly.
