Yellow skin discoloration on arm, lack of iron?

Could be a bruise you never noticed before and its almost healed....that happens to me alot. As for the red spots. Those should go away pretty quck. Shouldnt really worry. If you are since I understand your medical situation. Pick up some vitamins. They are expensive, but if you dieting or becoming a vegetarian you should be taking vitamins to replace all the nutrients your body needs that your not getting from all the other foods.
