Husband Sick

My husband has been sick now for at least a month. He has had so much nausea and they couldn't seem to find a cause. He spent two separate weeks in the hospital. They finally came up with the diagosis of congestive heart failure. He has all kinds of oxygen equipment now. We even have a tank in case the lights go out. It is a big help to have the County Nurse come in also to check on him.
