When to Go to the ER for Stomach Pain: What Every Parent Needs to Know

You know this feeling. Your child is curled up on the couch, hands pressed against their belly, and the pain isn’t going away. It started a few hours ago and it’s getting worse. They won’t eat, they barely want to drink, and you can see it in their face—something’s not right. You grab your phone, searching “when to go to ER for stomach pain.”

Stop. Before you load everyone into the car, you need to know something that could change everything about the next few hours.

Here’s what most parents don’t realize: Not all stomach pain is the same. Mild tummy aches from too much candy? That’s a clinic visit—or just time on the couch. But severe pain that’s getting worse, pain focused on the right lower side, vomiting that won’t stop, high fever with belly pain, or a rigid abdomen? That could be appendicitis, a bowel obstruction, or another surgical emergency. If your child’s stomach pain is severe or worsening, you need an ER with imaging and labs, not urgent care.

Urgent Care vs. ER for Stomach Pain: What’s the Actual Difference?

This isn’t about what sign is on the building. It’s about what’s inside the building—and whether they can actually diagnose what’s causing your child’s stomach pain. Understanding whether you need the ER or urgent care for abdominal pain is the first step.

Emergency physicians use something called the Pediatric Assessment Triangle to evaluate children in under 30 seconds. You can use the same approach at home.

A — Appearance: Is your child alert and responsive? Look for eye contact, normal crying with tears, and good muscle tone. Warning signs: limp or floppy body, won’t make eye contact, unusually quiet or inconsolable.

B — Breathing: Is breathing quiet and effortless? Can they speak in full sentences? Warning signs: visible rib movement with each breath, nasal flaring, grunting sounds, can only speak one or two words at a time.

C — Circulation: Is skin color normal? Are hands and feet warm? Warning signs: pale or gray skin, blue lips or fingertips, blotchy appearance, cold extremities.

If all three look normal, your child is likely stable—an urgent care visit or telemedicine may be appropriate. If any one of these looks abnormal, seek emergency care immediately.

⚠️ Urgent Care Can’t Diagnose Serious Stomach Pain

Urgent care clinics lack the CT scans, ultrasound, and full lab work needed to diagnose conditions like appendicitis, bowel obstructions, or internal injuries. If your child’s stomach pain is severe, they’ll just send you to the ER—wasting precious time. Every Priority ER location has on-site CT, ultrasound, X-ray, and a complete lab, and is truly open 24 hours a day, 365 days a year—including Christmas, Thanksgiving, and every other night when kids get sick.

When Urgent Care is Totally Fine

Not every stomachache is an emergency. Urgent care exists for a reason, and it can handle plenty of common childhood issues without the full power of an ER. Save yourself time and money when the situation calls for it.

LOW ACUITY

Conditions Appropriate for Urgent Care / Clinic

Stable vital signs • Alert and responsive • No respiratory distress

ENT / Respiratory
Otitis Media (Ear Infection)
Pain without high fever or drainage

ENT / Respiratory
Pharyngitis (Sore Throat)
Able to swallow, no drooling or stridor

Ophthalmologic
Conjunctivitis (Pink Eye)
No vision changes or severe swelling

Dermatologic
Minor Lacerations
<2cm, controlled bleeding, no tendon/nerve involvement

Febrile Illness
Low-Grade Fever (<102°F / 38.9°C)
Child >3 months, alert, drinking fluids

Dermatologic
Localized Rash
Non-petechial, not rapidly spreading

Musculoskeletal
Minor Sprains / Contusions
Weight-bearing, no deformity, normal circulation

Gastrointestinal
Mild Gastroenteritis
Tolerating oral fluids, no blood, no severe pain

The key word is mild. When stomach pain is manageable, your child is still drinking fluids, and there’s no fever or vomiting—urgent care during daytime hours works fine. But when things escalate, when the pain is getting worse or your instincts say this is different, that’s when you need to know when to go to the ER for stomach pain.

When Your Child Needs the ER Right Now

Parents know. There’s a difference between a tummy ache and “something’s really wrong.” Trust that instinct. Here’s what our severe abdominal pain emergency team says warrants knowing when to go to the ER for stomach pain:

Child with severe abdominal pain
Emergency

Severe Abdominal Pain

Pain that causes your child to double over, particularly right lower side pain which may indicate appendicitis. Rigid abdomen or pain that worsens rapidly.

Child with fever - thermometer showing high temperature
Emergency

High Fever with Stomach Pain

Fever over 103°F combined with abdominal pain signals infection. Could indicate appendicitis, peritonitis, or other serious conditions requiring immediate care.

Dehydration signs in children
Emergency

Severe Dehydration

No wet diapers for 8+ hours, no tears when crying, sunken soft spot in infants, or very dry mouth. Often accompanies vomiting or diarrhea with stomach pain.

Medical examination for vomiting
Emergency

Vomiting Blood or Bile

Vomiting blood, green bile, or material that looks like coffee grounds. Also concerning: vomiting that won’t stop or bloody/black stool with stomach pain.

Other emergencies that require immediate care include persistent vomiting with dehydration, stomach pain after trauma or injury, a distended or rigid abdomen, and inability to walk or stand upright due to pain. If your child has signs of appendicitis, don’t wait—this condition can become life-threatening if the appendix ruptures.

💡

Trust Your Parental Instincts

If something feels really wrong—even if you can’t explain why—go to the ER. Parents know their children better than anyone. That gut feeling exists for a reason.

Physician Exam (5-10 min)

A board-certified ER doctor examines your child and explains what’s next.

The Bottom Line for Parents

When you’re searching “when to go to ER for stomach pain” with a child doubled over in pain, you need a clear answer fast. If the pain is mild and your child is drinking fluids, wait for the doctor. But if pain is severe, getting worse, localized to the right side, or comes with fever—that’s when to go to the ER. Priority ER offers abdominal CT imaging to quickly diagnose appendicitis and other serious conditions.

Know the difference: urgent care handles mild tummy aches. Emergency rooms handle the serious stuff. And Priority ER gives you full emergency room capabilities—pediatric expertise, advanced imaging, on-site labs—without the chaos and wait times of a hospital ER.

When your instincts say something’s really wrong with your child’s stomach pain, trust them. And come to a place that can actually find out what’s going on.
