[|Human|] mty friend has had the same fever for 6 days and the doc saw him at home, said it was a viral infection. He has been given Migraleve but his fever is returning during the day and the bad headache at night - should we call the doc back in? He is soaking through all his sheets and bedclothes two and three times a day.
[|AI|]  Hello, Thank you for asking your query on ChatDoctorI appreciate your concern for your friend. A fever with no relief over 6 days cannot be taken for granted as viral fever. It requires to be investigated with blood tests and/or urine examination. If there is cough, X-ray of the chest also may be indicated. I think your friend should see the doctor again and he/she will decide what is best for him. Take care Chat Doctor.
