Hi and thanks for the query, What you describe is compatible with a bacterial throat infection. However this might need a clinical evaluation by your family physician. Pain, tender tonsils and the lesions on the tonsils are generally seen in Streptococal tonsillitis. the importance of treating early is to avoid spread and formation of abcesses which might require more invasive surgical drainage procedures. In some cases, persistence of this infection especially in children could exacerbate crises of rheumatic fever. It would be very appropriate to get a clinical evaluation to exclude other causes like Herpes infection and other vial infections that could present themselves in a similar manner. I suggest you book an appointment with your family care physician. thanks and best regards, Luchuo, MD.
