Addendum: To ear care info request. Important omission for evidence. I first experienced vertigo(?) In the hills of North Alabama at that time on that trip. No such problem on the boat trip last week just the same old ear, neck and headache from the low whine that can be turned up or down by remote control in someones control room right ear only of late or since the physical assault in my home last year one of the times. Remember I have no original keys the owner from hell does! Floyd Clifton Wooley
