We were diagnosed with bronchitis, prescribed Ospamox, nebulizer with saline solution, and also use furacilin for wiping and applying Nazivin drops. We clean the nose with saline solution. The nose is stuffed up when we clean it, clear mucus flows out, but there's something like a blockage in there, as if I haven't cleaned it completely. A strong cough comes with a whistling sound. My daughter couldn't sleep properly at night because of the cough. She's resting now. I don't know what to do anymore, it's heartbreaking that she suffered so much. She looks at me and cries. What day did your child experience coughing and stuffiness in their nose?
