@2late2be – Losing one’s sense of smell is not uncommon. Many cases resolve themselves over time, while others need medical treatment. Some of the causes include the following:
“The most common causes for loss of sense of taste and smell are the result of a nasal obstruction, such as the common cold, breathing allergies and nasal congestion from irritants like cigarette smoke and pollutants.
Nasal polyps, small non-cancerous growths in the nose and sinuses, can block the ability for aromas to reach the nerves high up in the nose which allow a sense of smell.
Previous surgery or a blow to the head can upset your sense of smell because the nerves of smell may be damaged or blocked by scar tissue.
Occupational exposure to chemicals may also lessen the sense of smell and certain medications can also affect the sense of smell.
Also, as we get older, like vision and hearing, the sense of smell becomes less accurate.
In rare instances, benign nonmalignant tumors grow on the nerves of smell and should be identified and removed.”
If you know you don’t have a cold or allergies, then I suggest visiting the doctor. It is very difficult to examine the inside of one’s own nose, so you need an expert to take a look.
