My brother (47 year old) get H1N1 on 17/2 and was in hospital for 10 days in Bangalore, He was having lung infection and was on oxygen for 5 days, his BP also went down during those days. He discharged on last sunday (26/2, for past 2 days he has again got fever 100-101 and with severe body ache specifically back and right hand side below hand. Doctor said that it might be because of viral fever as H1N1 has gone completely. Doctor has prescribed the pain killer and paracetamol? What is your advice on fast recovery? Can H1N1 symptom come back after 15 days or it is just viral fever? Does viral fever create muscle pain?
