Appendicitis: Sudden Relief Is an Emergency

Key takeaways

The strongest distinguishing feature of appendicitis is that the pain MOVES: vague around the navel, then after a few hours settling into the lower right abdomen and building — rather than being severe from the very start.
Severe pain that SUDDENLY EASES COMPLETELY is not recovery. It can be the moment the appendix bursts; after that the whole abdomen hurts and becomes board-hard. This is exactly the point at which many families breathe out in relief and lose the critical hours.
Before being seen: no strong painkillers and no antibiotics, no hot compress on the abdomen, no massage or coin-rubbing of the abdomen, no enemas or laxatives, and nothing to eat or drink once surgery is a possibility.
Young children, older adults and pregnant women often do not get the textbook pain — with them, lower the threshold for going in considerably.
Diagnosis needs an abdominal examination, blood tests and an ultrasound scan. Suspected appendicitis is a case for a medical facility, not a case to watch at home.

The thing that saves people, first: appendicitis pain usually MOVES. It starts vaguely around the navel, then after a few hours settles into the lower right abdomen — the right iliac fossa — and builds rather than easing. And the part many families read backwards: suddenly easing completely is not recovery.

Recognising it: pain that changes place

Appendicitis rarely opens with severe pain. Usually it is a dull ache around the navel, like indigestion, with loss of appetite and nausea. After a few hours the pain shifts down into the lower right abdomen and gradually worsens. Pain that CHANGES PLACE and then builds is the reliable sign, not how bad the pain is.

Loss of appetite almost always comes with it — not wanting to eat anything, even a favourite dish.
Nausea, vomiting once or twice, usually AFTER the pain rather than before.
A mild fever, chills; a high fever tends to come later, once there is a complication.
Constipation, or a few loose stools, with no relief afterwards.
How much or how little it hurts does not say how serious it is — do not use the level of pain as the measure.

Signs the family can see

A single cough, a deep breath or clearing the throat sends a sharp pain through the lower right abdomen.
Stepping down out of bed, or stamping the foot down, makes the pain worse; they walk slowly, slightly bent, holding the abdomen.
Going over a bump or a speed hump on the way makes the pain shoot up — whoever is taking them in notices this most clearly.
They lie with the knees drawn up for relief, and straightening the legs hurts more; they will not let anyone press on the abdomen.

Severe pain that suddenly eases completely

This is the most dangerous trap of all. An inflamed appendix swells under pressure and hurts severely; when it bursts, the pressure is released so the pain clearly subsides for a while. The family breathes out in relief and puts the person to bed — and loses exactly the most valuable window of time. The pain then returns, but ACROSS THE WHOLE ABDOMEN rather than in one place, the abdomen is board-hard, with a high fever and sweating. Sudden relief after severe pain is a reason to go to hospital NOW.

What to do straight away

Write down the TIME the pain started, where it was first, and when it moved to the right — the first thing a doctor asks.
Measure the temperature, note the time of the reading, and measure again a few hours later; do not estimate it by hand.
Let the person lie in whatever position is most comfortable, usually with the knees drawn up.
Note how many times they have vomited and whether they have opened their bowels; for a woman of childbearing age, note the date of the last period as well.
Gather the medicines they take and their documents; do not let the person drive themselves.

What NOT to do

Do NOT take strong painkillers and do NOT take antibiotics on your own before being seen: they make the abdomen less painful, less reactive to pressure, and bring the fever down, so the doctor loses exactly the signs used to make the diagnosis. Paracetamol (acetaminophen) is commonly used for pain and fever in general, but in a case of suspected appendicitis what is used is the doctor's decision.
Do NOT use a hot compress, a heat plaster or a hot water bottle on the abdomen — heat draws blood towards the inflamed area.
Do NOT massage, press hard, use coin-rubbing (cạo gió) or cupping (giác hơi) on the abdomen.
Do NOT give anything to eat or drink once surgery is a possibility, not even water: food still in the stomach delays the operation or raises the risk during anaesthesia. If they are thirsty, moisten the lips with water.
Do NOT give enemas, laxatives or anything “to help them go”: increased bowel contraction over an inflamed area is exactly what to avoid.
Do NOT wait to see whether it is better in the morning, once the pain has settled into the lower right abdomen and is building.

Three groups most often missed

The picture of “around the navel then moving to the lower right” belongs to healthy adults. The following three groups often do not follow it — lower your threshold for going in.

Young children: only unsettled, refusing to feed, refusing food, vomiting, lying curled up, unable to point to where it hurts; the younger they are, the sooner it can burst.
Older adults: mild pain, no fever, a soft abdomen, just eating poorly and being listless — easily labelled “a stomach upset”.
Pregnant women: the enlarging womb pushes the appendix upwards, so the pain can be in the upper right or in the flank.

What it gets confused with

Food poisoning: SEVERAL people ate the same meal and all became ill. If only ONE person has pain, the pain has settled into the lower right abdomen and is building, think appendicitis first.
A stone in the ureter: colicky pain in waves in the flank spreading down to the groin, restless and unable to lie still, and the urine may be pink.
Gynaecological conditions: pelvic inflammatory disease, a twisted ovarian cyst, and above all an ectopic pregnancy — in a woman of childbearing age with severe lower abdominal pain, that has to be ruled out first.

When you must go to hospital

GO TO EMERGENCY CARE, or call 115 (the emergency number in Vietnam), NOW if there is ANY of the following: pain settled in the lower right abdomen and building, with fever or vomiting; severe pain that SUDDENLY EASES COMPLETELY; pain spreading across the whole abdomen, the abdomen board-hard, not letting anyone touch it; high fever, fast heartbeat, sweating, cold hands and feet; continuous vomiting with no water staying down; a distended, tight abdomen, passing neither wind nor stool; drowsiness, listlessness. Lower the threshold considerably — go now even with milder signs — for young children, older adults, pregnant women, people with diabetes, and anyone taking corticosteroids. — BE SEEN THE SAME DAY, do not wait until tomorrow, if there is pain around the navel with loss of appetite and nausea lasting more than a few hours, or right-sided pain that is still mild but is not easing. After an appendix operation, if the wound becomes swollen and red, starts discharging, or the fever returns: be reviewed soon.

Suspected appendicitis is not something to manage at home: the diagnosis needs an abdominal examination, blood tests and an ultrasound scan. A Y Te Xanh (GreenCare) doctor or nurse can examine at your address and say clearly whether this is a case that must go in now or one that can still be watched; and after an operation we can care for the wound at home. If a sign in the box above is present, go to hospital first and call afterwards.

The advice not to take antibiotics belonging to someone else follows the guidance of the US CDC; this article passes that on and does not replace being examined in person. Citing CDC here does not imply that CDC endorses Y Te Xanh or our services.

Need personalised advice for your loved one? Call our hotline 094 368 81 15 (24/7) — calling to ask a question or to book costs nothing. GreenCare has doctors who come to examine, nurses who carry out doctor's orders (injections, infusions, dressing changes), remote consultation by video call, and a review of the medicines you are taking; an in-depth remote consultation, or any one after the first, is a paid service. For children we take examination and acute care only — not long-term care at home, and not newborns or expectant mothers. We confirm we have staff in your area and provide transparent pricing before we begin.

Frequently asked questions

Which side is appendicitis pain on?

In the end, the lower right abdomen — the right iliac fossa. But when it begins it usually does NOT hurt there: it is a vague dull ache around the navel, like indigestion, and only after a few hours does it settle down to the right and build. So “pain around the navel” does not rule out the appendix, and it is the pain changing place that is the most notable sign of all. In pregnant women, young children and older adults the location can be quite different.

How long before an appendix bursts?

There is no reliable time marker, and that is exactly why you should not wait. Some people develop over a day, some much faster, and young children usually faster than adults. Nobody can predict it from how it feels at home, so once the pain has settled into the lower right abdomen and is building, go and be seen rather than calculating how much time is left.

The pain stopped on its own — do I still need to go to hospital?

Yes, and this is a situation to go NOW. Pain stopping suddenly after a severe episode can be the moment the appendix bursts: the pressure inside is released so the pain subsides for a short while, before the whole abdomen becomes painful and rigid. Many families breathe out in relief and put the person to bed at exactly this point. If the pain beforehand was severe, treat sudden relief as a bad sign, not good news.

Should painkillers be taken while waiting to be seen?

Do not take strong painkillers on your own, and absolutely do not take antibiotics. They make the abdomen less painful, less reactive when the doctor presses on it, and bring the fever down, so the signs used to recognise appendicitis are blurred and the case is easily judged milder than it is. Paracetamol is commonly used for pain and fever in general, but in a case of suspected appendicitis whether to use anything, and what, has to be the doctor's decision after examining the abdomen.

Should I press on the abdomen myself to check?

Pressing gently once to find out where the pain is localised is fine, and that information is useful to the doctor. But do not press deeply, press repeatedly, or have someone else press hard to “test whether it is the appendix”: that only hurts the person more without adding any information. And absolutely no massage, coin-rubbing or cupping on a painful abdomen.

How do I tell appendicitis from food poisoning?

The most useful question is how many people are ill. Several people who ate the same meal and are all vomiting and passing loose stools within a similar window points to food poisoning. Whereas just ONE person with abdominal pain, the pain moving into the lower right abdomen and building, a clear loss of appetite and little vomiting, points to appendicitis and has to be seen. Nobody can tell for certain from how it feels — it needs an examination, blood tests and an ultrasound scan.
