 [ Symptoms ] how long should i wait before bringing my 11 yr old with flu symptoms to our family dr it has been 8 days initial symptoms were nausea high fever severe headache loss of appetite and fatigue those lasted about 2 days now she is very tired little appetite sore bellynausea and has a sore throat and cough [ Disease ] hi that is how we all get after flu just treat her cough with a cough medicine which should sort out her throat as well and slowly her appetite will come back when that happens her strength will come back as well and she will feel a better so cant see why you need a doctor good luck
