Thank you very much for the useful information Brad.
Well there are many reasons for abnormal taste/smell sensations in mouth/nose...These include;
2. Gastroesophageal Reflux disease
3. Aging (due to loss of taste buds and impaired smell sensations)
4. Upper respiratory infections, including sinus infections/allergies
5. Any injury to mouth, nose
6. Chemotherapeutic agents
7. Poor oro-dental hygiene
8. Fungal infections in the mouth or tongue area
9. Dental infections
Another important differential in your case is Phantosmia. Phantosmia, also known as olfactory hallucinations (false perceptions of abnormal smells), are actually smell odours that are not derived from a physical stimulus.
Most common causes of phantosmia include upper respiratory infection (like sinusitis), brain tumor, seizure disorder, alzheimer's disease, or idiopathic ( where no cause can be found out ).
If 2-3 weeks have passed with out any improvement in your symptoms, it would be a standard guideline to see your doctor again discussing the above mentioned possibilities, which will direct further tests and subsequent management plan.
At home, avoid spicy foods.
Add flavours to your food.
Take plenty of juices and fruits---these all will help.
Prilosec OTC can also be tried to control reflux, if present.
I would have been worried too if i were at your place but let me reassure you that this is a treatable condition and carries a good prognosis with appropriate management.
It was a pleasure assisting you and thank you very much for visiting us.
