Hello, I m a 53 year old woman. I m in generally good health and don t take any medications other than occasional allergy med (not recently) or excedrine for occasional headach. As of about a week ago, I ve had a couple of Charlie horses in my calve in the early morning hours. They went away with no lingering problem. Last night, early this morning, I woke to go to the restroom and was extremely dizzy when I sat up. Once stable, I walked to the bathroom but had to hold onto furniture to keep from falling over. I stayed home from work and slept. I feel better now but have slight dizziness if I lay down or change my head position. Should I worry if this resolves itself by tomorrow?
