my wife is dizzy sweats ,, nausea, off balance, headache, weak . she was just released from hospital and they said it was mystery benign positional verdago, what the heck... she cant function like this.. they don't know what it is . Not heart attack, not a stroke, no fever, no infections. What do I do next?? it killing me to see her this way. She would normally outwork anybody you know . Now she can't even walk on her own to the car
