Ever since I've had my first child, I've had moments where I start to get lightheaded, my legs feel really weak and I have to grab something to help hold me up, my vision grays out around the edges, sometimes completely covering my vision, making me blind. I get shortness of breath and can still think proper thought but cant seem to make myself make any noise. After anywhere from a few seconds to even a full minute my vision comes back and I feel fine, all except the headache afterwards that fades away after another minute or two. It can happen seemingly anytime; maybe 2-3 times a day to 2-3 times a mth whether I'm doing normal activites or not. I admit to not having medicare so I havent had this checked by a doctor, but I wanted to know if it was just something simple that can be helped with a change of diet or even just a certain vitamin before I even tried a doctor. Can anyone help?
