My husband, 81 yrs. old, began the week with runny nose & coughing, Friday eve following dinner hour he broke out with chills and a fever. To bed he went. Saturday am the same. Never took temp because do not have the means. He has been letting Ricola , sugar free, Herb Throat Drops dissolve in throat daily. As of yesterday he has taken 500 mg. Tylonal every four hours He also is drinking water during waking hours, and a Gatorade once a day. He feels less warm to the touch today. What else could we do?
