The symptoms as mentioned in your post suggest that you might be having Vertigo associated with dysosmia
It can be attributed to:
1. Some medications like metronidazole
2. Exposure to certain chemical
3. Upper respiratory tract
infection in the form of common cold
or sinus infection
4. Poor oral hygiene
, anxiety, etc.
7. Abnormal levels of blood pressure & blood sugar values
A proper examination of the ear, nose & throat will be helpful in clinching the diagnosis.
So, it will be better to consult an ENT specialist
& get a proper physical examination done to rule out any organic lesion.
So that appropriate management steps could be taken.
There is nothing to worry...you will be fine.
Wishing you a Good Health. Let me know if I need to clarify further.
Thanks & take care.
