I ve been feeling quite shakey lately. It s worse when I stand/ am walking, but I also feel it when sitting or laying down. I get a wave of feeling very warm and have cold sweats hits me, my head gets lightheaded (a bit starry), and my body gets tingly (almost feels numb). When up it feels like I m on the verge of fainting, so much so that I have to hold on to something/ brace myself to keep myself up. Could this be a sign of low iron, or an electrolyte imbalance?
