Your symptoms seem to be caused by a throat infection (commonly known as strep throat).
Paracetamol will help with fever and body ache but will only give temporary relief. You need an antibiotic along with a paracetamol.
That being said, these symptoms might also be caused due to other conditions which will require further tests and evaluation.
You require a doctor consultation for detailed symptom evaluation and prescription, kindly get in touch with a physician.
