4. Breathlessness
If you struggle to ascend the stairs without gasping for air, or if you feel like you can never quite get a proper intake of air, then this could also be a symptom of bronchitis.
The role of the bronchial tubes is of course to take air to the lungs and so when they become inflamed, they might become partially blocked. Meanwhile, you might find that mucus makes its way into the lungs, thereby causing a rattling sound and making it hard to fill them with air.
