Smoking?: Most common is chronic damage to nerves of the nose and tongue from toxic exposure. Your complaints are very common for smokers or those who use asthma inhalers too much. Heavy metal toxicity can cause these symptoms. Lead, mercury and arsenic exposure can cause this. A thorough medical evaluation would be appropriate.
