When you have asthma, any infection – a cold, virus, flu – can affect the lungs, causing inflammation and bronchoconstriction (airway narrowing). It is important to take measures to stay healthy and be aware of any lung symptoms, even mild, so that you avoid an asthma attack.
What symptoms suggest I have an asthma-related infection?
Call your doctor if you experience any of the warning signs of an infection (listed below). Also call your doctor if you have any other symptoms that cause concern:
- Increased shortness of breath, difficulty breathing, or wheezing
- Increased need for your reliever medication (rescue inhaler)
- Coughing up increased amounts of mucus
- Yellow- or green-colored mucus
- Fever (temperature over 101°F) or chills
- Increased fatigue or weakness
- Sore throat, scratchy throat, or pain when swallowing
- Sinus drainage, nasal congestion, headaches, or tenderness along upper cheekbones
