At times i can be lying down and all of a sudden i get a weird feeling of dizziness, i get weak, nauseated and the urge to go to the bathroom. All of this makes me really weak for about an hour. I have been having this problem for about 4 years now. I must add that last year I started having heart palpitations, where my heart will all of a sudden start racing from 160 to 210 beats per minute with my blood pressure rising during my episode. I don't know if the two are related in any way so I thought I would add my heart condition in there with my other symptoms. Can anyone help me?
