Hi,
Chronic lightheadedness only on left side (not lightheaded on right side) and forehead over 3 months, on and off tinnitus in ears, feel dull pressure on left ear, and also in cheek bone,no hearing loss. Brain CECT scan, cervical spine xray, blood report, vit
b12, vit d, Audiometry and tympanometry all normal. Ct PNS shows mild sinusitis, but nothing serious. Doctors say nothing wrong with ears, based on above investigation. Have been to multiple ENTs, Neurologist, taken medication for vertigo, antihistamines, but no help. What could be the possible diagnosis, since no specialist I have consulted has been able to help.
