Thanks for using healthcare magic.
I have gone through your available history.
It seems that your viral infection is the reason for your symptoms like sweating, headache lack of energy etc.
you should consult your doctor for detailed evaluation if fever
is still present.
Doctor may advise you to go for blood tests like hemogram, billirubin level or widal
tests to rue out other possible cause of fever.
Treatment should be directed as per cause.
Please take adequate amount of water, ORS
powder or lemon juice to maintain hydration.
I hope It will help you.
