I'm so done with this bronchitis ? My son has been sick for 3 weeks, he coughs up phlegm, we've already taken antibiotics and injections for a week, and we've been doing inhalations with a nebulizer first, then just a physical solution, at home we have a humidifier, I ventilate often, I do drainage massage, the doctor says if there are wheezes by Thursday, then again injections will be prescribed only twice a day ? and they won't take him to the hospital, there's only space in the corridor ? in short, I came here to cry ? my son has never been sick for so long.
