My Husband has nausea, fever, achy hands, feet and extremely tired. Last year he had a bone infection in his foot from an open wound that started around a callous. He was on numerous antibiotics, had hyberbaric oxyen therapy, finally surgery on his foot. Right now he is telling me he feels like he did when the infection was at its worse. Recently other family members had the stomach flu which he already had, so I don't think thats what he has now. I want him to go to the doctors but, he doean't want to. What could it be?
