well, my legs feel weird and i am tired and i get dissy when i change postions. I asked my mother what all of thosemeans she said my sister had the same thing and she has low iron. I have been playing basketball alot and sweating. I read on a yahoo answer that if you pull your eye down and if it is white it means your low on iron and i pulled my down and it was white and i asked my mom and my dad to show me theres and it was a pinkish color. What should i do? also i have been taking vitamins with 100 percent iron. Whats wrong with me? is it okay if i play basketball or will something happen? Also i am out of energy. also the last 2 days my ribs hurt like i am hungrey, but i ate and it comes back.
