What to do if…
you notice chest discomfort plus new jaw, shoulder, or arm pain without a clear cause

Short answer

Call 911 now — chest discomfort with new jaw/shoulder/arm pain can be a heart emergency even if you’re unsure.

Do not do these things

  • Do not drive yourself to the ER or have someone rush you in a car unless 911 tells you to.
  • Do not wait it out or try to “prove” it’s nothing by walking around, showering, or lying flat.
  • Do not take extra/new painkillers (like ibuprofen/naproxen) to see if it improves — it can delay calling for help or mask changing symptoms.
  • Do not take someone else’s prescription heart medicine.
  • Do not take aspirin unless 911 advises it or you were previously told by a clinician to do so for suspected heart attack — and avoid it if you have an aspirin allergy or have been told not to take it.

What to do now

  1. Stop activity and sit upright (or half-sitting). Try to keep movement minimal.
  2. Call 911 and say: “Chest discomfort with new jaw/shoulder/arm pain.”
    • If you’re alone, put the phone on speaker and keep it with you.
  3. Follow the dispatcher’s instructions exactly.
    • Ask: “Should I chew an aspirin?”
  4. If advised (or if your clinician previously told you to do this for suspected heart attack) and you are not allergic and have not been told to avoid aspirin:
    • Chew and swallow immediate-release aspirin 162–325 mg (often 325 mg).
    • Do not give aspirin to children or teens (under 18).
    • If there’s any uncertainty, it’s reasonable to wait for EMS rather than take aspirin.
  5. If you have prescribed nitroglycerin for angina/chest pain, use it exactly as prescribed and tell 911 you used it (including the time and dose). Do not take it if it is not yours.
  6. Make access easy for EMS: unlock the door, turn on a light, and if possible have someone wait outside to guide them in.
  7. Collect key info (quickly):
    • the time symptoms started
    • your medications (especially blood thinners), allergies, and major conditions (heart disease, stents, stroke, recent surgery, pregnancy, major bleeding history)
    • emergency contact
  8. If you feel worse (increasing pain, shortness of breath, fainting), tell 911 immediately.
  9. If you (or the person) become unresponsive and not breathing normally, the dispatcher can guide you: start CPR and send someone to get an AED if one is nearby.

What can wait

  • Deciding whether it’s “definitely” a heart attack.
  • Calling your primary care office first.
  • Searching symptoms online or trying to self-triage.
  • Packing a bag, contacting work, or arranging childcare — EMS can help you figure out next steps after you’re safe.

Important reassurance

Many people delay because symptoms feel vague or “not bad enough,” or they worry about being wrong. Calling 911 for chest discomfort with jaw/arm/shoulder pain is an appropriate safety step — rapid evaluation matters.

Scope note

These are first steps only for the next minutes. EMS and the ER will assess and treat the cause; later decisions can wait until you’re stabilized.

Important note

This is general information, not medical advice or a diagnosis. If you have these symptoms now, calling 911 is the safest choice.
