my son had viral fever two weeks back..but only for 1 day and had given dolo only 3 times.. even all family members got that fever, he was fine. now everyone recovered. now again he got fever. this time he had 99.2C morning and evening 100.9C yesterday. today he had no fever as i checked his temperature but his head is always slightly hot..now again I checked his temperature at 2:15pm, it is showing 99.2C. Why so? should I give him dolo? since it's low grade fever should I take him to hospital. why is he having fever again after 12 days..
