When to Go to the Emergency Room for Abdominal Pain

Sudden or severe abdominal pain is a reason to come now. Call 911 for pain with collapse, confusion, vomiting blood, or a rigid abdomen. Severe pain plus vaginal bleeding in anyone who could be pregnant is an emergency — go immediately.

The American College of Emergency Physicians gives three separate triggers in one sentence, and the way people read that sentence matters enormously:

“If the pain is sudden, severe or does not ease within 30 minutes, seek emergency medical care.”

Sudden. Or severe. Or not easing within 30 minutes. Three independent reasons, any one of which is enough.

The thirty minutes is not a waiting period. It is there to catch the pain that never becomes dramatic and never goes away — the kind people sit with for six hours. If the pain is sudden or severe, the clock is irrelevant and you should not start one.

Why abdominal pain is genuinely hard, and not just for you

The abdomen contains a great many organs, and several of them produce nearly identical pain when something goes seriously wrong. That is why this is the symptom where “wait and see” is most tempting and least reliable.

ACEP’s framing is blunt: “Sudden abdominal pain is often an indicator of serious intra-abdominal disease.” Sudden onset is information in itself, separate from how bad it feels.

And on the combination that matters most: “Continuous, severe abdominal pain—or abdominal pain accompanied by continuous vomiting—may indicate a serious or life-threatening condition.”

Pain that will not stop, or pain with vomiting that will not stop. Those two pictures are the ones to act on rather than to time.

The one that is a race, and it is easy to miss

Severe abdominal pain with vaginal bleeding, in anybody who could be pregnant, is how ACEP describes an ectopic pregnancy — and it is an emergency in which time genuinely changes the outcome.

It does not require a positive test, a confirmed pregnancy, or a missed period to be worth acting on. If that combination describes you, go now, and say those two symptoms in that order at the desk.

What appendicitis actually looks like, which is not what people expect

ACEP names the signs: “severe pain (usually in the lower right abdomen, but may start anywhere in the abdomen), loss of appetite, nausea, vomiting or fever.”

Read the clause in the brackets. The lower-right rule is a usually, and the pain may start anywhere in the abdomen. A great many people have delayed because the pain was in the wrong place for the diagnosis they had in mind.

And loss of appetite is on the list, which almost nobody counts as a symptom worth reporting. Mention it.

And pancreatitis, which behaves differently again

ACEP’s description: “pain in the middle upper abdomen that may last for a few days. The pain may become severe and constant, or it may be sudden and intense” — with “nausea, a swollen and tender abdomen, fever and a rapid pulse.”

Note the duration. Days. A pain that has been there for three days and is getting worse is not disqualified from being an emergency by having lasted a while.

The trap this page has to close

Upper abdominal pain can be a heart problem, and “it is my stomach” is one of the commonest reasons people wait.

Indigestion, a rich meal, reflux, a stomach bug — there is always an available explanation, and that explanation is often correct. But a page listing abdominal causes hands you reasons to discount a cardiac symptom, so this page is going to close that door itself.

If there is chest pressure, pain spreading to the arm, jaw, neck or back, breathlessness, cold sweat, or nausea with a feeling of doom — treat it as cardiac and call 911. What to do about chest pain does not change because the pain is lower than you expected.

Call 911 rather than driving

• Pain with collapse, fainting, or confusion
• Vomiting blood, or black or tarry stools
• A rigid, board-like abdomen
• Pain after significant injury to the abdomen
• Severe pain with vaginal bleeding in anybody who could be pregnant
• Pain with chest pressure or breathlessness

The National Library of Medicine’s guidance on recognising medical emergencies puts severe or persistent pain, changes in alertness and uncontrolled bleeding in the same category: these are situations for an ambulance rather than a car.

Come in, without calling first

• Sudden pain, however it feels now
• Severe pain, at any location
• Pain that has not eased within 30 minutes
• Pain with continuous vomiting
• Pain with fever
• Pain with a swollen or tender abdomen
• Pain in a young child, an older adult, or anybody with a serious ongoing condition
• Pain that is getting worse over hours or days

Our emergency rooms are open every hour of every day and are walk-in, with CT, X-ray and a full laboratory in the building — which is most of what answering an abdominal question requires. Go to the nearest one, and if another emergency department is closer to you, that one is the right answer tonight.

And for mild pain

ACEP’s own advice for mild pain is to contact your doctor first, and that is sensible — a clinic can examine you, arrange testing and follow the pattern over time. Our clinics are open Monday to Thursday and Friday mornings, with appointments by phone.

That is routing, not a refusal. ACEP is equally clear on the other side: “Anyone who thinks they’re having a medical emergency should not hesitate to seek care.”

If you are unsure, come in — this list is not exhaustive and you are not expected to work out which organ is involved.

Questions people actually ask

It is bad but I can still walk and talk. Is that an emergency? Being able to walk does not rule anything out. Sudden or severe, or not easing in 30 minutes, is the standard — and none of those requires you to be incapacitated.

Should I take something for the pain before I come? Come as you are. This page gives no doses, and pain relief taken on the way is worth mentioning at the desk rather than hiding.

Should I eat or drink first? Better not to, if you think you may need imaging or a procedure. Mention when you last ate.

It comes and goes. Does that mean it is fine? No. Colicky pain that comes in waves is a recognised pattern for several serious problems. If the waves are severe, that is severe pain.

My child has a stomach ache and is off their food. Loss of appetite is on ACEP’s appendicitis list. A child with abdominal pain who will not eat, who is guarding their tummy, or who has a fever should be seen.

I am pregnant and have abdominal pain. Be seen. Abdominal pain in pregnancy is not something to assess from a web page, and severe pain with bleeding is an immediate emergency.

It has been three days and it is getting worse. Duration does not make it less urgent — pancreatitis in ACEP’s own description can run for days. Getting worse is the part that matters.

---

Sudden, severe, or not easing within 30 minutes — any one of those is a reason to come, and the thirty minutes is not a waiting instruction. Call 911 for collapse, confusion, vomiting blood, or severe pain with bleeding in pregnancy. Both of our emergency rooms are open 24 hours a day, every day of the year — walk in, no appointment and no referral. Find your nearest emergency room →
