Hello. Son is 2.5 years old. In December, he had bronchitis, with wheezing in his bronchi. He was treated with an oral antibiotic. Two months have passed. We've been sick again. And you know, if someone has fever, sore throat first, then we start coughing immediately in our first day. And it's not dry, but with phlegm right away. And wheezing appears. When he sleeps, it can be heard. The cough is good, watery. But there was fever for 5 days. We started Summed again today. The doctor came and said there's still wheezing in his bronchi. We need to do tests, send him to an infectious disease specialist
