You should get your ears and throat checked at first.
Congestion in the nasopharynx can block the eustachean tubes and this might cause such a feeling. Impacted wax can also cause same feelings.
The other possible causes are inner ear problems- like labyrinthitis, viral vestibular neuronitis, menieres disease of the semi circular canals.
Still , other causes possible are- cerebellar lesions, low/ high BP, low blood sugar, and sometimes hyperacidity and anxiety.
Benign positional vertigo is a common cause in the elderly women, but its a diagnosis of exclusion.
I suggest , you go for a detailed investigation , in consultation with the ENT ,so that we can arrive at an early diagnosis.
