Had too much blood

My husband had too much iron in his blood. Four to six times a year, he had to have blood drawn. The doctors said he would have to do this for the rest of his life. It is now five to six years since the doctors discovered that he had too much iron in his blood. When you have this condition, there is a risk of heart attack. A year and a half ago, I called you and received prayer. You prayed for him over the phone. Something happened then. Since then, he hasn't needed to have blood drawn anymore. The iron content in his blood is perfectly normal now. The doctors don’t understand it at all.
