I have been having episodes of hearing loss in left ear. Sometimes lasts minutes hours and recently days. Starts as pressure like water in ears, have been checked by ENT no wax no fluid and audio shows slight decline In left ear. My hearing comes back but I have ringing, humming sound. Taking Benadryl this time helped hearing return. Dr mentioned many possibilities, my concern is I m flying out in 2hrs a3hour flight, he mentioned mini ear stroke what is that... My hearing was distorted this time like hearing someone through a glass... Is it safe to fly?
