I've had a viral infection hitting 3wks on monday, no temperture, iron low at 7 but have spots around hip area and down side under armpits area?

Cannot diagnose. Without seeing you and examining these there is no way to tell what they are. If your serum iron is only 7 you need to learn how anemic you may be and why you are either not absorbing iron or losing it through bleeding. See a doctor and have this worked out. Good luck.
