Dry cough and throat infections can have many causes, including viral infections, allergies, irritants, or bacterial infections. It’s important to identify the root cause before taking any medication. Antibiotics like amoxicillin should never be used on your own, because improper use can cause side effects, complications, and antibiotic resistance. A healthcare professional can properly evaluate the infection and safely prescribe the most appropriate treatment.

Frequent mouth infections after a tonsil operation suggest lingering bacteria, poor oral healing, or an immune-related issue. Maintain strict oral hygiene, avoid irritants, and consult your doctor for evaluation, possible cultures, and proper treatment to prevent recurrent infections.
