What is the ER for?
Last updated September 3, 2026.
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.

What to do
- Memorize the short list: chest pain, stroke signs, breathing trouble, major trauma.
- Do not drive yourself in the big ones: call 911.
- Weeks-old problem? Wrong door: book a regular visit instead.
- Unsure? Triage first: a two-minute check beats a four-figure bill.
