💡TL;DR: Acute bronchitis usually is not something you can cure overnight. Most people start to feel better within about 2 to 3 weeks, but the cough can last longer while the airways heal. Antibiotics usually do not help because most cases are caused by viruses, so the fastest path

💡TL;DR: For adults 60 and older, one RSV vaccine dose protects for at least two RSV seasons, so it is not a yearly shot. In babies, protection is much shorter: the maternal RSV vaccine helps protect a newborn for about 6 months, and the infant antibody shot lasts about

💡TL;DR: Walking pneumonia is a milder form of pneumonia that often feels like a long‑lasting chest cold, with a nagging cough, tiredness, and chest discomfort that can stretch on for weeks. Fever may be low or even absent, so pay more attention to how long your cough and

💡TL;DR: Shortness of breath when you lie flat is called orthopnea and it usually points to a heart or lung issue that needs checking. If it eases when you sit up or you need two or more pillows to sleep, schedule a medical visit; sudden or severe symptoms are

💡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
