question: Hi! My 18 month old had hand, foot and mouth disease last week and passed it along to my husband. Little blisters began to form on his hands, feet and mouth on Friday but is still not feeling any better. He has a cough (he s had over two weeks), low fever, mild headache and feels light headed. My impression of the diseases was that he should be feeling better after the blisters appeared but that does not seem to be the case. He feels worse now than he did Friday. Should he see a doctor tomorrow?
