Hi, Welcome to Health care magic forum.
As you describe, it is acute
throat infection, and it is to be treated care fully.
I advise you to consult a physician for diagnosis and treatment.
I usually prescribe to my patient with such symptoms
erythromycin 500mg, twice daily, phenylefrine, citrizine,
paracetamol, till the diagnosis is established.
Avoid taking fruits, juices, icewater, icecream, etc.
Wishing for a quick and complete recovery. Thank you.
