Hi Dear,
Welcome to HCM.
Understanding your concer. As per your query you have dizziness and
sinus infection and vertigo. Well there can be many reasons for vertigo , but the most common is anxiety and the other Benign paroxysmal positional vertigo (BPPV) are
ear infection , hypoglycemia , anemia , meniere's disease , migraine 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 . Avoid caffeine product and bending froward .
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
