Go to an emergency room now if abdominal pain is sudden and severe, if your belly is rigid or tender to the lightest touch, if the pain comes with a fever, persistent vomiting, or blood, or if it is getting steadily worse rather than easing. Those features point to appendicitis, a gallbladder attack, a bowel obstruction, a perforation, or internal bleeding — conditions where hours matter.
Most stomach aches are not emergencies. The trick is knowing which ones announce themselves differently.
Go to the ER now
Do not wait for a morning appointment if you have:
- Sudden, severe pain that arrived like a switch being flipped
- A rigid, board-like abdomen, or pain so sharp you cannot bear light pressure
- Pain with a fever and chills
- Persistent vomiting — nothing staying down
- Blood: vomiting blood or coffee-ground material, or black, tarry, or bloody stools
- Pain that started near the navel and moved to the lower right — the classic appendicitis migration
- Severe pain in the upper right abdomen, especially a few hours after a fatty meal, possibly spreading to the right shoulder blade
- Pain radiating to the back with vomiting, which can mean pancreatitis — or, with sudden tearing pain and faintness, an aortic emergency
- A swollen, tense belly with no bowel movement or passing of gas
- Abdominal pain in pregnancy, or with vaginal bleeding
- Pain after abdominal trauma — a fall, a crash, a hard blow
- Pain with dizziness, fainting, or a racing heart, which can signal internal bleeding
- Pain in someone over 65, immunosuppressed, or diabetic — these groups can have serious disease with deceptively mild symptoms
What the location suggests
Not a diagnosis, but useful orientation:
| Where it hurts | Commonly suggests |
|---|---|
| Lower right | Appendicitis; ovarian problems; kidney stone |
| Upper right | Gallstones, gallbladder inflammation, liver |
| Upper middle | Ulcer, gastritis, pancreatitis, sometimes cardiac |
| Lower left | Diverticulitis; constipation; ovarian problems |
| Around the navel, then moving | Early appendicitis; small bowel |
| Flank, radiating to the groin | Kidney stone — often waves of severe pain with nausea |
| Everywhere, with rigidity | Perforation or widespread inflammation — an emergency |
A point worth making: pain that starts vague and becomes localised is a pattern that deserves attention. Appendicitis classically begins as an ill-defined ache near the navel and settles into a specific tender spot in the lower right over several hours.
The things people get wrong at home
Painkillers are usually fine — laxatives and heat are not. Old advice said avoid pain relief before evaluation in case it masks the diagnosis; modern practice does not support withholding it, and emergency physicians will treat your pain. What you should not do is take laxatives or enemas for unexplained severe pain, because if there is an obstruction or inflamed appendix you can make things considerably worse. Avoid a heating pad on severe localised pain for the same reason.
Don’t eat or drink if you suspect you may need surgery, until a clinician says otherwise.
“It got better” is not always reassuring. If severe appendicitis pain suddenly vanishes, it can mean the appendix has ruptured and the pressure has released — followed by a much sicker patient a few hours later. Sudden relief after severe pain is a reason to be seen, not a reason to relax.
Arizona-specific causes
Dehydration and kidney stones. Arizona sits in the “stone belt” for a reason: chronic mild dehydration concentrates urine, and concentrated urine forms stones. Kidney stone pain is often described as among the worst pain people experience — waves of severe flank pain radiating to the groin, with nausea and blood in the urine. Come in. We can confirm it with a CT scan on site, control the pain, and check whether it is obstructing.
Heat illness. Nausea and abdominal cramping are early heat-exhaustion symptoms and are easy to mistake for a stomach bug after a summer hike.
Food-borne illness. Most cases settle at home with fluids. Come in for bloody diarrhoea, a high fever, signs of dehydration, or symptoms lasting more than a few days — and sooner for young children and older adults.
What we can find out, and how fast
This is where a fully equipped emergency room differs sharply from an urgent care, most of which cannot image your abdomen at all. At our Emergency Room we have, in the building:
- CT scanning — the workhorse test for appendicitis, obstruction, diverticulitis, and kidney stones
- Ultrasound — first-line for gallbladder disease, and for pregnancy, where it avoids radiation
- A full laboratory — white cell count, liver and pancreatic enzymes, kidney function, urinalysis, pregnancy testing
- X-ray, and board-certified providers on site around the clock
- Intravenous fluids, anti-sickness medication, and pain relief while we work it out
If you need surgery, we stabilise you and arrange transfer to a hospital, with the receiving team briefed by your provider here.
When the clinic is the right call
Book a Medical Clinic appointment for abdominal discomfort that is:
- Long-standing or recurring without red flags — bloating, cramping, irregular bowel habits
- Mild and settling, such as a stomach bug you are keeping ahead of with fluids
- Reflux or heartburn you would like properly managed
- Constipation, food intolerance, or a pattern you want investigated
- Follow-up after an ER visit
Same-day appointments are usually available: (602) 671-7981.
Where to go
Call 911 for severe pain with fainting, a rigid abdomen, vomiting blood, or pain after major trauma.
Come to our Emergency Room — 9700 N. Saguaro Blvd, open 24 hours, no appointment — for any of the red flags above, or if the pain is severe and you are not sure. ER: (602) 671-7990.
Book the Medical Clinic for chronic, mild, or recurring abdominal symptoms.
