Thanks. I'm worried about my 11-year old who has seemed "not himself" for a month: fatigue, lethargy, body aches, off and on chills. Last two days: intense chills in body, especially legs. No fever. Blood tests at the doctor's last week show all is normal except evidence of a virus.



I have had a terrible, exhausting cold; he could just be coming down with it, minus the upper respiratory symptoms because we have given him zinc lozenges for the last 4 days or so. But he's been unwell for so much longer than this. Thanks!
