Lately I've been having pain in both my knees, my nose has been bleeding almost every morning, I have cravings for tape, and I get fatigued easily. When I was 3 or 4 I had anemiadue to low levels of iron, so I was wondering if these symptoms of anemia coming back or not? Oh and also I was doing really good in school in the past years but know I seem to get distracted and I am not doing very well... please help
