Random dizziness attacks. Includes tingling all over body: Legs, arms, hands, certain areas of brain, back etc. Also includes a cloudy vision. I also feel very scared. When I am sitting down I get dizzy but when I get up and walk around I feel fine. I have many nosebleeds and lose blood resulting in an iron deficiency. I have been taking iron supplements and have fixed the nosebleed problem and have been fine. Today I had a nosebleed and have experienced this again. Is this a result of my iron deficiency, or is it anxiety or a combination. I am also curious as to why only part of my head tingles. (This time it was the back right corner of my brain but it differs every time)
