my husband was seen a week and a half ago with chills, severe sweating, low grade temp, vomitting. The called it Viral Syndrome. Chems and CBC were normal as well as liver enzymes. little high blood sugar and small amount of sugar in his urine. Felt better after 4 days of rest. Yesterday he complained of a sore throat and felt like he was getting a chest cold. Today he has vomitted twice, is sweating profusely and has the chills. any suggestions of what this could be? Flu? Different virus than last week?
