No but the morons at the hospital forgot to tell you to take potassium, magnesium and calcium chelate so that it doesnt happen again. Iron deficency test: Go to the mirror and pull your lower eyelid and see if the color is red or flesh color. If its flesh colored you are lacking enough iron and should take a herbal iron like Floradix. It will take a month to see a difference. Iron carrys oxygen in your blood and if you dont have it you will feel tired, cold hands and feet, headaches, RLS, dull brittle hair, brittle nails, poor sleep, pale skin (see thru), shortness of breath, fatigue, poor concentration, low mood, ringing in the ears, cracks in the corner of the mouth, dizziness, fainting, sore tongue and canker sores oh and pale mucous membranes in lower eyelid.
