My friend for several weeks has reoccurring weakness, headaches,fatigue , nausea and vomiting, fever, hypertension at times confusion. Then has periods of days when he is ok. They have ruled out heart attack, aneurism , questioning west Nile , runs temp at times, weakness can be extreme . In the last week to er five times....sent home then admitted to hospital twice but, they can t figure it out. Today at hospital ordered stomach cat scan. His pain in head a ten. Old head injury from fall a couple years ago took year to fully recover. He is 65 yr old male. This is a smaller hospital. We are worried! Thank you, Sherry Aginah
