💡TL;DR: Empyema = around the lung; lung abscess = inside the lung. Empyema usually needs drainage plus antibiotics; a lung abscess usually responds to antibiotics alone. CT is the best way to tell them apart; a classic study found CT correctly distinguished them in every case. Empyema carries higher short-term risk

💡TL;DR: Valley Fever can leave a small lung nodule (a scar) in about 5% of infections, and most are harmless and do not become cancer. In endemic areas, many nodules that look suspicious on scans prove to be Valley Fever scars; doctors balance watchful follow-up vs biopsy based on

💡TL;DR: Empyema is an infected pleural effusion (pus in the pleural space) that usually needs urgent drainage plus IV antibiotics, while a typical pleural effusion is extra fluid that is often not infected and is treated by fixing the cause and draining only if needed. Doctors look for loculations

💡TL;DR: A nebulizer can help COVID-related wheeze or chest tightness, especially if you have asthma or COPD, but it does not treat the virus. If you already have a prescription, keep using it as directed; if you do not, talk to your doctor before starting any nebulized medicine. Use

💡TL;DR: Effusion = fluid; pneumothorax = air that can collapse a lung. Effusions are common in the U.S. (≈1.5 million cases yearly), while spontaneous pneumothorax is less common but often sudden. Imaging separates them quickly (fluid layering vs a clear rim of air), and treatment differs: effusion is drained

💡TL;DR: Pulmonary edema is fluid inside the lung’s air sacs; pleural effusion is fluid around the lungs in the pleural space. Edema tends to be sudden and is an emergency, treated in the hospital with oxygen and diuretics; effusions often build gradually and can be drained while the

💡TL;DR: ALS weakens the breathing muscles, not the lungs, so early clues are orthopnea, morning headaches, daytime sleepiness, and a weaker cough. Starting noninvasive ventilation at night when tests and symptoms change can improve sleep and daytime energy and is linked to longer survival. Airway clearance tools (assisted cough,

💡TL;DR: RSV can cause a skin rash, but it is uncommon and usually mild. Most rashes appear around days 3–5 of illness and fade within 3–7 days. The bigger risk with RSV is breathing problems, not the rash. Seek care fast for trouble breathing, blue lips/skin,

💡TL;DR: Most upper respiratory infections (URIs) are contagious because they are caused by viruses that spread easily through droplets and on your hands. You are usually most contagious in the first 2–3 days of symptoms and can spread infection for about 3–10 days overall. Stay home while
