Hello everyone, I need your advice. My daughter has a sore throat but not in her nose, but in her throat, I don't even know how to explain it. We called the doctor, he prescribed some candles and drops of Aquamaris for children, but there is no effect. Has anyone ever encountered this? What did they do? I'm also doing massage, maybe they will come out through the cracks gradually. I don't even know how we got infected ?
