My husband has been sick for 10-12 days. Weak, pain in hips and legs, temp 99-101, sweats, lack of energy, sleeping a lot, blood work is off - hct 33, other s out of normal range, pale or waxy yellowish color, lack of appetite - just looks and acts sick. He s not a complainer. Recently he learned his PSA has doubled in 9 mo. following a rad prostatectomy Jan 2012. I m worried! Family doctor said viral infection. Can that be?
