Hi, my husband just drove himself to urgent care. The last 2 to 3 days he has been experiencing white spots when he turns his head. He sees them on the left side. He s been under a lot of stress the last few days, and not getting enough sleep. He is 72, but in very good health and in good physical shape. He walks and bikes several times a week! He says that it happened before a few years ago when under a lot of stress. He also says that he hasn t had any headaches.
