I feel you have acute tonsillitis
. Though you are taking the correct medicine, i do not know whether you are taking correct dosage or not. It should be 625 mg twice a day for minimum of 7 days , along with analgesics and anti inflammatory drugs. And also at least thrice a day throat gargling with some antiseptic lotion or warm saline.
I cannot opine about Neuflo
, since its an alternative medicine.
