Since you have experienced symptoms for six months without relief, the most definitive and effective cure for chronic tonsillitis is a surgical procedure called a tonsillectomy. When infections persist despite medical therapy, the tonsils can harbor resistant bacteria. A tonsillectomy is a very common, routine procedure that permanently resolves the issue. Before considering surgery, an ENT specialist might try one final targeted course of generic antibiotics like amoxicillin-clavulanate or clindamycin, guided by a throat swab culture. Please consult an Ear, Nose, and Throat (ENT) specialist to discuss whether a targeted medication or a simple surgical removal is the best step forward for you.
