Liver pain typically feels like a dull ache or throbbing in the upper right side of your abdomen, just below your ribcage. The liver itself doesn’t have pain receptors. Instead, the discomfort comes from a thin layer of connective tissue that surrounds the organ, called Glisson’s capsule. When the liver swells, becomes inflamed, or is pressed on by a growth, this capsule stretches, and that stretching is what you actually feel. Because the capsule sends signals through the same nerves as nearby organs, liver pain often feels diffuse and hard to pinpoint, sometimes radiating to your right shoulder or back.
Why Liver Pain Feels Vague
Pain originating from internal organs behaves differently than pain from, say, a cut on your skin. Organ pain is processed more diffusely by your nervous system, which is why liver discomfort can feel like a general heaviness or pressure rather than a sharp, localized sensation. This also makes it easy to confuse with gallbladder pain, stomach issues, or even a muscle strain. The shared nerve pathways between the liver and the diaphragm explain why some people feel liver-related pain in their right shoulder, a phenomenon called referred pain.
Fatty Liver Disease
One of the most common causes of liver pain today is fatty liver disease, a condition where excess fat accumulates in liver cells. The non-alcoholic form affects roughly 1 in 4 adults worldwide and is closely tied to obesity, insulin resistance, and high triglycerides. In its early stage, fat buildup alone can cause the liver to enlarge, stretching Glisson’s capsule and producing that characteristic dull ache under the right ribs.
Many people with fatty liver have no symptoms at all, which means pain, when it does appear, can signal that the condition has progressed. When fat accumulation triggers ongoing inflammation, the condition advances to a more serious stage that can lead to scarring (fibrosis) and eventually cirrhosis. At that point, the liver may be significantly enlarged or hardened, and the discomfort becomes more persistent.
Alcohol-Related Liver Damage
Chronic heavy drinking damages the liver in a well-defined progression: fatty liver first, then fibrosis, then cirrhosis. The troubling reality is that this process typically unfolds over a decade or more and is largely silent. Most people experience no symptoms until the damage is advanced. Pain, when it finally shows up, usually means the liver has already developed significant inflammation or scarring. By the time someone with alcohol-related liver disease notices persistent right-sided abdominal discomfort, the condition has often reached a stage that requires serious medical attention.
Hepatitis and Other Infections
Viral hepatitis, particularly hepatitis A, B, and C, causes liver inflammation that can produce upper abdominal pain. With acute hepatitis B, for example, symptoms include stomach pain, nausea, fever, joint pain, dark urine, and yellowing of the skin or eyes (jaundice). These symptoms develop relatively quickly and can be quite uncomfortable.
Chronic hepatitis B and C are a different story. Symptoms can take decades to develop, and many people carry these viruses without knowing it. When pain does emerge from chronic hepatitis, it often means the virus has caused enough cumulative damage to enlarge or scar the liver. This is one reason routine screening matters, especially for hepatitis C, which is now curable with treatment.
Bacterial infections can also cause liver pain through abscess formation. A liver abscess is a pocket of pus that develops inside the organ, and it produces more acute symptoms: fever occurs in about 90% of cases, and abdominal pain in 50 to 75%. Some people also experience right shoulder pain from irritation of the nerve that runs along the diaphragm, along with chills, night sweats, and unexplained weight loss.
Liver Cysts and Growths
Small liver cysts are extremely common and almost never cause problems. Most are found incidentally during imaging done for other reasons. Pain from a liver cyst typically doesn’t start until the cyst reaches about 10 centimeters in diameter, at which point it’s large enough to compress surrounding structures. At that size, cysts can press on bile ducts or blood vessels, causing symptoms that range from a dull ache to more specific problems like jaundice or bile duct obstruction.
Liver cancer, most commonly hepatocellular carcinoma, is another cause of liver pain. Right upper quadrant abdominal pain is one of the most frequently reported symptoms. The pain comes from the tumor physically encroaching on surrounding tissue and stretching the liver capsule. In some cases, liver cancer spreads to bone, which happens in roughly 3 to 20% of patients and introduces a different type of pain entirely. Early-stage liver cancer often causes no pain at all, which is why people with known risk factors (chronic hepatitis, cirrhosis, heavy alcohol use) are typically monitored with periodic imaging.
Liver Pain vs. Gallbladder Pain
Because the gallbladder sits just beneath the liver, it’s easy to mistake one for the other. Gallbladder pain has some distinguishing features that can help you tell them apart. A gallstone attack typically comes on suddenly and intensifies rapidly, centered in the upper right abdomen or just below the breastbone. It often radiates to the back between the shoulder blades or to the right shoulder, and it’s frequently accompanied by nausea or vomiting. The key difference is timing: gallbladder attacks usually last minutes to a few hours and then resolve, while liver pain tends to be more constant and low-grade.
That said, the overlap is significant enough that imaging is usually needed to sort out the source. An ultrasound can quickly reveal gallstones, an enlarged liver, cysts, or other structural problems.
How the Source Gets Identified
If you’re experiencing persistent pain in your upper right abdomen, doctors typically start with two things: blood work and imaging. Blood tests measure enzymes and proteins that indicate how well the liver is functioning and whether it’s inflamed or damaged. These tests also screen for hepatitis viruses, check blood sugar and cholesterol levels (which point toward fatty liver disease), and assess how well the liver is producing proteins needed for blood clotting.
Ultrasound is usually the first imaging step because it’s fast, noninvasive, and good at detecting fatty liver, cysts, tumors, gallstones, and signs of cirrhosis. Depending on what the ultrasound shows, a CT scan or MRI may follow for a closer look. In some cases, a biopsy is needed to determine the exact type and severity of liver damage.
Symptoms That Need Urgent Attention
Most liver pain develops gradually and reflects a chronic process. But certain accompanying symptoms signal something more serious. Yellowing of the skin or eyes (jaundice) means the liver is struggling to process bilirubin, a waste product from red blood cells. Abdominal swelling from fluid buildup, called ascites, suggests the liver’s blood flow is significantly obstructed. Dark urine paired with clay-colored stools points to a blockage in bile flow. And abdominal pain severe enough that you can’t stay still or find a comfortable position warrants immediate medical evaluation.
Fever combined with right-sided abdominal pain raises concern for a liver abscess or acute infection, both of which can deteriorate quickly without treatment. Unexplained weight loss alongside liver pain is another red flag, particularly for cancer or advanced liver disease.
