Acute bronchitis typically has a sudden onset, usually accompanied by symptoms such as coughing, expectoration, or chest tightness and breathing difficulties. During such times, it's recommended to follow a doctor’s guidance and possibly use nebulized inhalation for treatment and symptom relief. This may involve inhaling steroids or bronchodilator medications to alleviate symptoms. Additionally, it is important to maintain fresh and flowing air indoors, with appropriate temperature and humidity levels.
