I am 26 years old, over weight but my blood pressure is exceptional...I also suffer from sleep apnea and cataplexy. I was wondering if I might be having a mini stroke. On 3 different occasions over the past couple years I have lost perpherrial vision in one eye...sort of looks like I have a big black spot in the way of seeing and sometimes it's pulsating. I also lose feeling in my fingers and palm of my hand. Im not sure if I am giving myself these numbness from having a panic attack from being scared of losing my eyesite or is it something more serious? It usually only lasts for less than an hour or so and then I am fine.
