What to do if…
you have sudden chest pain after a long trip or prolonged immobility

Short answer

Call 999 now for an ambulance if the chest pain is sudden, severe, doesn’t go away, or you’re short of breath, sweaty, nauseated, light-headed, or feel faint. Do not drive yourself.

Do not do these things

  • Do not “wait and see” or try to sleep it off.
  • Do not drive yourself to A&E or ask someone to speed you there.
  • Do not walk around to “test it” or try to stretch it out.
  • Do not take indigestion remedies or painkillers to delay getting help or to “see if it’s serious”.
  • Do not massage a painful/swollen leg.
  • Do not eat a large meal, drink alcohol, or smoke to “calm down”.
  • Do not take aspirin instead of calling 999.

What to do now

  1. Call 999 immediately and say: “I have sudden chest pain after a long trip / long period of sitting still.”
    • Tell them if you have difficulty breathing, pain worse on breathing/coughing, coughing blood, a very fast heartbeat, fainting/near-fainting, or one leg that’s swollen/painful.
  2. Stop what you’re doing and rest. Sit upright or in the position that makes breathing easiest. Keep movements minimal.
  3. If you have someone with you, ask them to stay and help.
    • Ask them to bring your phone, charger, front door key, a list of medicines, and any inhalers/GTN spray you normally use.
  4. If you are alone, make access easy for the ambulance crew (without exerting yourself).
    • Unlock the door (or put the key in the lock if safe), turn on a light, and keep your phone on speaker near you.
  5. Aspirin: only after calling 999, and only if appropriate.
    • If the 999 call handler advises it, follow their instructions.
    • If you strongly suspect a heart attack-type pain (heavy/pressure/tight central chest pain, possibly spreading to arm/jaw/back, with sweating/nausea/breathlessness) and an adult aspirin (300mg) is already within reach, it may help to chew and swallow one 300mg tablet while waiting — only if you are not allergic, are not under 16, have not been told to avoid aspirin, and are not on blood thinners / do not have a known bleeding disorder.
  6. If you have prescribed GTN (glyceryl trinitrate) for angina, use it only as you’ve been told to.
    • If this pain is new, severe, different from your usual angina, or not easing quickly, treat it as an emergency and do not wait to call 999.
  7. If someone collapses or stops breathing, the bystander should call 999 (if not already) and start CPR and use an AED if available.

What can wait

  • Working out whether it’s a clot, heart problem, muscle strain, reflux, anxiety, or something else.
  • Phoning your GP or NHS 111 (these are for non-emergency advice, not sudden serious chest symptoms).
  • Searching online, finishing your journey, or “just getting home first”.
  • Sorting travel admin (tickets, insurance, notifying work/family) until you’re safe.

Important reassurance

Chest pain after prolonged immobility can be caused by several things, but some are time-critical and can look “not that bad” at first. Calling 999 is the right move if you’re unsure.

Scope note

This is first steps only to keep you safe in the moment. Hospital clinicians may need tests to rule out serious causes, and any follow-up plan depends on what they find.

Important note

This guide provides general, immediate safety steps and is not a diagnosis. If symptoms are severe, new, worsening, or you feel something is seriously wrong, treat it as an emergency and call 999.
