Fever for last 3 days. Or test.

High fever for last 3 days. I had minor allergic symptoms on Friday, 26/07/19. Took anti allergy medicine but late in night started experiencing high fever 102 f with headache and body ache. Took paracetamol but no relief in fever.No other major cold or throat infection symptoms. Visited Doctor next day. He could not see any major infection but very minor throat infection. Prescribed Clarithromycin 500 mg twice a day , montair FX and paracetamol tab. Have taken 4 dosage but still have 100 f fever. I am not very sure whether antibiotics was really required as I was not experiencing any discomfort in my throat . As per doctor, there is possibility of bacterial infection because paracetamol was not effective Please advise should I wait for 1-2 days and continue with present medicine or need some other medications or test.
