The ER is for threats to life, limb, and eyesight: chest pain (MedlinePlus: call 911 immediately - sooner treatment saves heart muscle), stroke signs (the CDC: every minute counts), breathing trouble, severe allergic reactions, major trauma, uncontrolled bleeding, severe burns, poisoning, seizures, and high fever in infants under 3 months.
What it is not for: colds, refills, chronic flare-ups, and week-old problems - those wait behind real emergencies and generate the biggest bills. The rule of thumb: could this kill or maim in the next few hours? Then the ER. Everything else starts at urgent care, telehealth, or a doctor's visit. Pymander is a free AI doctor, 24/7 by text, and can help you make the call in the moment.

Common questions
What is the ER for?
The emergency room exists for threats to life, limb, and eyesight - the problems where minutes change outcomes. The core list: chest pain or pressure (possible heart attack - MedlinePlus's heart-attack guidance is blunt: call 911 immediately, because sooner treatment means more heart saved); stroke signs - sudden face drooping, arm weakness, speech trouble, the worst headache of your life (the CDC's stroke guidance: every minute counts, because treatment windows are measured in hours); difficulty breathing; severe allergic reactions; major trauma - car crashes, falls from height, deep wounds, suspected broken necks or backs; uncontrolled bleeding; severe burns; poisoning and overdoses; seizures; and high fever in an infant under 3 months. What the ER is not for, despite the lines: colds, prescription refills, chronic-pain flare-ups, rashes, and anything that started weeks ago - those wait behind the genuine emergencies and generate the system's biggest bills. The rule of thumb: if the question is 'could this kill or maim me in the next few hours,' it is the ER; everything else starts at urgent care, telehealth, or a doctor's visit.
