It often hurts to exercise or stand for long periods of time. Now the doctor says it may be caused by either eating sushi or eating ice. For some reason, I've been consuming large quantities of ice, just eating it and craving more. He said I may be freezing the hemoglobin in my intestines and getting a form of anemia that might cause the swelling. I'd never heard of that and wanted a second opinion.
Pica is the urge to eat different substances.
It is common to have the urge to eat ice with iron deficiency anemia. This is not the cause of the anemia, but a symptom seen in some patients. Something is causing your blood loss and this needs to be investigated. Your doctor has the problem backwards. Secondly, sushi does not cause swelling or anemia.
