Dear friend, welcome to HCM !
Your symptoms fit a viral illness.
Flu is nothing but influenza
viral illness... nothing different.
Do you have feverishness, cough
, cold, runny nose?
You could take rest and advil
and cold tablets, some steam inhalation at home and observe yourself.
Viral illnesses usually get better in 3-5 days.
Watch for any rash
, high fever
, giddiness etc.
Take care and please keep me informed of your progress.
Good Luck !
I hope to have answered your query satisfactorily.
