I m 39, slim (BMI 22) and healthy - apart from hypotension. I ve been light headed for 2 days, with nausea. Vision became a bit blurry for a few hours midday today and then went but since then i ve had pins and needles, slightly in my hands, then more so in my foot and now slightly in both lower legs, despite having my legs out flat? I saw a doctor who checked me after blurred vision and she checked my eyes etc but the pins and needles have come on since then
