Hi before 2y I suffered BPPV. But after physical exercise by ent specialist I feel good. But now this problem come again. At the time of sleeping when I roll my self to left side I feel fast dizziness. But when I turn only neck to left side I feel noting. Vertigo come only when I turn my body to left side. I go to the ent doctor he examine with physical exercise but nothing found. My neck muscles are stretch. In x ray they found nothing. Please tell me why I feel dizziness. After a fast spinning I feel spinnning in all my movement and feel imbalance. Please help me to what it is.
