Sorry to hear about your problem.
Do you have anyother associated symptoms like hearing loss, ringing or buzzing in the ear.
What do you feel while being dizzy i.e. you just feel unsteady or the room seems to rotating.
How long this attack remains once it begin?
Are there peroids when you feel completely ok?
Do you have any eyesight problem?
You are most likely suffering from some ear problem and thats is causing these symptoms most likely. I am a consultant ENT specialist and usually come across such patients.
You need to visit ENT doctor in your area who will evaluate you by doing clinical exam and audiometric and imaging investigations if required to rule out any neurological cause.
Ear problems usually take time to settle and need special precautions.
Eye problems are also associated with ear problem because of the coordination between the tracts going from ear and eye to brain.
All the best
Lot of prayers for you and your sweet kids
Yes very right. ENT is together because ear nose and throat are connected to each other. There is a possibilty that your sinus prob might have affected your ear and now that ear is giving these problems.
Anyhow visit your ENT again and ask for ear tests also. And i am sure you will get fine after getting proper treatment.
Your well wisher
