My Dad is in his early 60's. He has been very ill for over two weeks. He has severe back pain, vomiting early on but better now still doing it a little, fever, no apetite at all. He had Prostrate Cancer a couple of years ago. He is so weak he can barely walk around the VA told him he had the flu and go home. Please help he showed up at my house tonight he has lost alot of weight, face looks drawn, tears in his eyes, I am sure he is dehidrated.
