As per your query you have dizziness along with palpitations and headache. The symptoms you mention in query can occur due to many reasons like benign paroxysmal positional vertigo , Vertigo may also be caused by inflammation within the inner ear sometimes due to infection , meniere's disease ,
acoustic neuroma ,
sinusitis and cardiac problem. Sometimes
ear infection occur due to postnasal drip due to sinusitis. In this case the infection spread through eustachian tube and cause ear infection. I suggest you to consult with
ENT specialist for proper checkup so that there will not be any further complication . Doctor may order certain test like CT scan , MRI ,
blood test , audiometery test , rotatory chair test and ECG to confirm the diagnosis . Doctor may prescribe ant emetic drug , sedatives , antibiotics , decongestants ,drain sinus and some ear aid . Doctor may also refer you to cardiologist. For now avoid bending foreword , take steam , drink ginger tea thrice a day and do light exercises daily .
Hope your concern has been resolved.
Get Well Soon.
