Hello and welcome to HCM
The symptoms of vertigo
(spinning of head) on changing position of head points towards some pathology of the inner ear
Inner ear is responsible for maintainance of balance and equilibrium.
This may occur due to head trauma
, infection or idiopathic (without any cause).
Vertigo can also occur in cases of cervical spodylosis.
You need to get a complete otolaryngiological examination, audiometry
and MRI head to know the exact cause of the symptoms.
