hi there, what you have just described fits into the diagnosis of benign paroxysmal positional vertigo which is not an uncommon condition. Your husband may be right in suggesting that you have an ear infection
and that cannot be ruled out. It is believed to be due to a mechanical malfunction of the inner ear
. It can be effectively treated with repositioning movements such as the Epley maneuver
.You should visit an ENT specialist
and rule out other causes of vertigo so that he can start an effective treatment. Take care.
