It starts as a dull ache. Maybe it’s a sharp poke when you twist to grab your seatbelt. Or perhaps it’s that weird, heavy pressure that only shows up after a big Mexican dinner. When your right ribs hurt, your brain immediately goes to the scary stuff. Is it my liver? Am I having a gallbladder attack? Did I somehow break a bone while sleeping?
Honestly, the area under your right ribcage is crowded. You've got the liver, the gallbladder, the right kidney (tucked toward the back), the tail end of your pancreas, and a whole lot of "ascending" colon. Then there’s the musculoskeletal stuff—the intercostal muscles that sit between your ribs and the cartilage that holds the whole cage together. Because so much is packed into that one zip code, the pain can be incredibly vague. Doctors often call this Right Upper Quadrant (RUQ) pain.
But here’s the thing: most people wait too long to figure out the "why" because they’re afraid of what they’ll find. Or, they assume it’s just gas. Sometimes it is. Other times, your body is waving a giant red flag.
The Gallbladder: The Usual Suspect
If the pain is sharp and happens about thirty minutes after you eat a greasy burger, your gallbladder is the most likely culprit. This tiny, pear-shaped sac stores bile. When you eat fat, it squeezes that bile into your small intestine. If you have gallstones—which are basically little pebbles of hardened cholesterol or bilirubin—that squeezing process becomes a nightmare.
Biliary colic is the medical term for this. It’s not a constant throb. It’s a rhythmic, intense squeezing. Dr. Peter Magee, a gastroenterologist, often notes that patients feel this pain radiating straight through to their right shoulder blade. It’s a weird "referred pain" quirk of our nervous system. If the stone gets stuck in a duct, you’re looking at cholecystitis (inflammation). That’s when you get the fever and the nausea. If you're turning a bit yellow—jaundice—that's an emergency. Don't wait.
When It’s Actually Your Muscles
Sometimes the reason your right ribs hurt has nothing to do with your organs.

Costochondritis sounds terrifying but it’s just a fancy word for "inflamed rib cartilage." You can get this from a nasty cough, lifting a heavy box awkwardly, or even intense stress that causes you to tense your chest muscles. The hallmark of costochondritis is that it’s "reproducible." If you push on the spot with your finger and it hurts more, it’s likely a skeletal or muscular issue, not an internal organ. Your liver doesn't care if you poke your skin; your cartilage does.
Then there are the intercostal strains. These are the tiny muscles between your ribs. You use them every time you breathe. If you’ve been golfing, rowing, or even just sneezing violently from allergies, you can pull these. It feels like a localized, sharp stitch. It’s annoying. It takes forever to heal because, well, you can't stop breathing to let the muscle rest.
The Liver and "The Silent Ache"
People worry about their liver because it's massive and sits right there. But the liver itself doesn't actually have pain receptors. The Glisson’s capsule—the thin layer of tissue surrounding the liver—does. For your liver to hurt, it usually has to be swollen enough to stretch that capsule.
Fatty liver disease (NAFLD) is becoming incredibly common. Most people don't feel it until it’s quite advanced, but some report a dull, heavy fullness in the right side. It’s less of a "pain" and more of a "presence." According to data from the American Liver Foundation, nearly 25% of adults in the U.S. have some form of fatty liver. It’s usually caught on an ultrasound for something else. If the ache is accompanied by extreme fatigue or a swollen abdomen, that’s when the liver moves from "maybe" to "definitely get a blood test."
Gas, Bloating, and the Hepatic Flexure
This is the one nobody talks about. Your colon has a sharp turn right under your right ribs called the hepatic flexure. If gas gets trapped in that specific corner, it can cause an incredibly sharp, stabbing pain that feels like it’s deep inside your chest.

It’s often mistaken for something much worse. You might feel like you can't take a full breath. Then, you burp or... well, you know... and the pain magically vanishes. This is often linked to Irritable Bowel Syndrome (IBS) or just eating too much broccoli and beans. If the pain moves around or disappears after a bowel movement, your guts are the likely culprit.
Pleurisy and the Lung Connection
The bottom of your right lung sits right above the diaphragm, which sits right above your liver. If the lining of your lungs (the pleura) becomes inflamed—usually from a viral infection like the flu or pneumonia—it causes pleurisy.
This pain is very specific. It’s "pleuritic," meaning it hurts specifically when you inhale. It’s a sharp, stabbing sensation. You might find yourself taking shallow breaths because deep ones are too painful. If you have a cough or a fever along with that right-side rib pain, your lungs are the first place a doctor is going to listen with a stethoscope.
Kidney Stones: The Back-to-Front Slider
While your kidneys are technically in your "flank" (your back/side area), a stone moving through the right ureter can cause pain that radiates toward the front right ribs and down into the groin. This isn't a dull ache. It's often described as the worst pain imaginable. It comes in waves. One minute you're fine, the next you're on the floor. If you see blood in your urine or the pain is making you vomit, it’s probably a stone.
Assessing the Situation: A Quick Checklist
Because right ribs hurt for so many reasons, you have to be a bit of a detective. Ask yourself these specific questions:

- Is it tender to the touch? If yes, think muscles, ribs, or cartilage.
- Does it happen after eating? If yes, think gallbladder or stomach/intestines.
- Does it hurt more when you breathe in? If yes, think pleurisy or a strained intercostal muscle.
- Is it a dull "fullness" or a sharp "stab"? Fullness points toward the liver or chronic gallbladder issues; stabs point toward gas, stones, or acute injury.
- Do you have "red flag" symptoms? Fever, yellowing of the eyes (jaundice), tea-colored urine, or pale, clay-colored stools are signs that you need a doctor immediately.
What You Should Actually Do Next
You shouldn't just sit there and wonder. If the pain is new, persistent, or worsening, you need a professional opinion.
First, track your triggers. For three days, write down what you eat and when the pain starts. This is gold for a doctor. If you tell a GP, "It hurts on the right," they'll run twenty tests. If you tell them, "It hurts specifically 20 minutes after I eat dairy or fried food," they’ll head straight for a gallbladder ultrasound.
Second, check your posture. We spend so much time "tech-necking" over laptops that our rib cages actually compress. This can pinch nerves and irritate the small muscles between the ribs. Sometimes, simply using a lumbar support or doing basic "open book" stretches can alleviate that nagging right-side ache.
Third, look at your supplements. High doses of certain fat-soluble vitamins or even excessive acetaminophen (Tylenol) use can stress the liver. Be honest with yourself about your alcohol intake, too. The liver is resilient, but it’s not invincible.
Finally, get an imaging test if the pain sticks around for more than a week. A simple abdominal ultrasound is non-invasive, relatively cheap, and can see gallstones, liver swelling, and kidney stones in about fifteen minutes. It’s the fastest way to get peace of mind.
Stop Googling "cancer" at 2 AM. Most of the time, rib pain is a mechanical issue or a digestive hiccup. But because the liver and gallbladder are in that neighborhood, "watching and waiting" isn't a great long-term strategy. Get the ultrasound, fix your posture, and maybe cut back on the deep-fried appetizers for a week to see if things settle down.
The next step is simple: book a basic physical and ask specifically for a "liver function panel" blood test and an abdominal ultrasound. These two tests cover about 80% of the common causes for pain in that area. If those come back clean, you can breathe a sigh of relief and head to a physical therapist to work on those rib muscles.
