Hi Dear,
Welcome to HCM.
Understanding your concern. As per your query you have dizziness, sinus and ringing in the ears. Well there can be many reasons for tinnitus or ringing in ear along with dizziness and sinusitis , but the most common is anxiety and the other Benign paroxysmal positional vertigo (BPPV) are
ear infection ,
hypoglycemia , anemia , meniere's disease , upper respiratory track infection and alteration in he blood circulation . Ear infection sometimes occur when infection spread from
post nasal drip , which further occur due to sinusitis . Infection spread to ear through eustachian tube . So it is possible that you get infection now . Dizziness is a symptom of vertigo . I would suggest you to
consult ENT specialist for proper examination . Doctor may order certain test like CT scan for sinusitis , MRI ,
blood test , audiometery test, and ECG to confirm the diagnosis.Doctor may prescribe antiemetic drug alon with antibiotics (
gentamicin ) and anti allergic . i would like to suggest you some
home remedies drink green tea with ginger thrice a day and drink lots of fluids like juices and water .
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
