I'm female, 42, and have a history of dance and am very active. I had a seizure disorder as a child but haven't been treated since I was 12 after EEG was normal. Several times over the past 5 years or so, while dancing or doing aerobics I have had episodes in which my arms and legs just seize up and I can't control my movement. At the same time, there's an almost electrical pop in my brain and my vision is temporarily disrupted. It all happens in just a split second, but it's very disorienting and frightening. Think of it as a sudden electrical surge. I have no idea what to think and whether I should go see a doctor. Any thoughts?
