💡TL;DR: Allergic asthma is triggered by allergens like pollen or dust mites, while non-allergic asthma flares with things like viral infections, cold air, smoke, strong odors, or exercise. The symptoms feel the same; the difference is the trigger, and allergic asthma more often starts in childhood while non-allergic asthma

💡TL;DR: Hemoptysis = blood with a cough from the lungs; hematemesis = blood with vomiting from the stomach or esophagus. Look for bright, frothy blood in mucus during a cough versus dark coffee‑ground or bright red blood mixed with food after nausea. Any vomiting of blood warrants emergency care; coughing

💡TL;DR: Yes, pneumonia can be contagious when it is caused by a virus or bacteria, and it spreads at close range in cough and sneeze droplets. Viral cases are contagious for several days. Bacterial cases usually stop spreading about 24–48 hours after effective antibiotics. Walking pneumonia (Mycoplasma) can

💡TL;DR: Bronchitis irritates the airways and is usually viral; pneumonia infects the lung's air sacs and tends to be more severe. Expect bronchitis to improve in 1–3 weeks and pneumonia to take 1–2+ weeks, with fatigue lingering. Antibiotics usually don't help acute bronchitis,

💡TL;DR: After COVID-19, a new or returning low fever, a cough that worsens instead of easing, and new shortness of breath within 1–3 weeks can signal walking pneumonia. See your doctor to confirm with a chest X-ray; don’t assume it’s just long COVID. Most people feel

💡TL;DR: Chest pain that worsens with deep breaths often points to pleurisy, while pain you can reproduce by pressing the chest usually means costochondritis. Musculoskeletal chest wall pain is common in primary care (about 20–40%) and costochondritis is a frequent cause, while pleurisy signals inflammation of the lung

💡 TL;DR: Use your rescue inhaler 10–15 minutes before exercise and warm up for 10 minutes — these two steps prevent most episodes. Quick-relief inhalers protect for about 2–4 hours; if you need them often, a daily inhaled steroid or an ICS/formoterol plan can cut symptoms. Montelukast may

💡TL;DR: Use your quick-relief inhaler first, then sit upright and breathe slowly; that is the fastest way to calm a night asthma cough. Nights are tougher because of your body clock, lying flat, cool dry air, and bedroom allergens. To prevent wake-ups, take controller meds on schedule, sleep on
