Thank you for posting your query on XXXXXXX
Well looking into your problem I would like to tell you that you will need to consult an ENT specialist
for this , your symptoms are suggestive that it could be BPPV , Benign paroxysmal positional vertigo
, it can lead to dizzy feeling or a spinning sensation in people in particular position .
You will need to be examined for that in person so I will advise to see an ENT specialist or a neurologist
for this as considering your age other causes relating to nervous system like syncope
etc also needs to be ruled out.
