Hi well come to hcm.
It looks like viral infection, take paracetamol
at the interval of 6 to 8 hrs, and some
syrup like, Tossex, Dilosyn, foe symptomatic relief. Viral in fection is self limiting
so you should be all right in 3 to 4 days and if not consult your doctor and if needed get
done blood reports as per his advise. thanks
