I don t know which specialist to ask, so I ll start with you. For the last week, I ve been having dizzy spells. The first occurred last Sunday, early in the morning. I got up to use the bathroom, and when I laid back down, my head started spinning out of control. Then yesterday, I was drying my hair and bent over to dry the back of my head. The spinning started immediately. I stood up and faced the mirror. I wondered if I was having a stroke . I could smile and lift my arms. It slowly subsided. It occurred again this morning when I laid back down on my bed, after a visit to the bathroom. It s a scary, out of control feeling. I am 64. I am concerned about possible circulation problems.
