I had an attack of extreme dizziness which rendered me incapable of walking or even standing. I was taken to the hospital i was X-rayed, MRI of my head, Ultasound of my heart, caroidt arteries, and complete blood work up. All were pretty much normal. I was discharge still having bouts of dizzy spells although they are becoming less frequent and less severe. I am having moderate pain in the area of my left ear. How should I proceed
