I am suffering from severe head spin while twisting and turning while sleeping, and sometimes during drinking water direct from bottle or even picking something from floor. Whenever head movements are happening, some level of uneasiness is experienced. But dizziness while in sleep was massive during last few days , as if so, I had to hold my pillow, as I was feeling that I will fall down. Which doc should I consult. What has happened to me ? I have never faced this before. Is this because of vertigo or spondylitis?? I have taken vertin 16 and stemitil (sos), relief was short spanned .
