HI I have gone through your mail, as you said that you have sinus problem and now you developed vertigo and vomiting. You are also having chest problem as bronchitis
. After considering your complaints I am telling you that your problems are inter related,as your sinus infection
is giving rise to post nasal drip
thus infection reaches to throat and from here reaches to your ear via Eustachian tube (tubular connection between ear and throat ), inside the ear it had got affected the vestibule of inner ear
,this vestibule of inner ear maintains balance of your body so once vestibule is affected imbalance occurs which is medically called as vertigo.You are having chest infection
(bronchitis) which also sends infection to throat and from throat it passes to ear in same as explained above.Thus yur problems are inter related.Thanks.
