Hi, I have seizures along with a number of other strange symptoms although they still cannot figure out why. Initially, they even thought it might have been psychological but, as time goes on that opinion seems to be less and less likely as they discover more and more. I'm only 19. I'm not overweight, and I have stage 2 Nash moving close to stage 3. Last night as I closed my eyes I began to see flashes of light. Every time I saw the light flash I felt like my entire body was being electrocuted, shocked, or tased. It was incredibly painful. Going to the emergency room or just calling my average doctor is about useless now and a waste of money since they can never find anything. The painful shocking sensation is new. Should I be concerned? Do you know what this is?
