Pain in the upper right part of your abdomen, just below the ribs, usually signals that your liver is swollen, inflamed, or pressing against surrounding tissue. The liver itself has very few pain-sensing nerves, so the discomfort you feel comes from stretching of the membrane that surrounds it (called the capsule) or from pressure on nearby organs. Several conditions can trigger this, ranging from temporary and treatable to serious and progressive.
Why the Liver Produces Pain
Your liver sits behind your lower right ribs and weighs about three pounds. The organ’s interior tissue doesn’t have pain receptors, which is why many liver diseases develop silently for years. What does hurt is the thin capsule wrapped around the liver. When the liver swells from inflammation, fat buildup, infection, or a growing mass, that capsule stretches, and you feel a dull ache or pressure on your right side. In some cases, the swollen liver also pushes against the stomach or diaphragm, which can cause referred pain in the right shoulder or chest.
Fatty Liver Disease
Excess fat accumulating inside liver cells is the most common liver condition worldwide, and it’s one of the most frequent reasons people notice a vague discomfort on their right side. In its early stage, fatty liver rarely causes symptoms. But when the fat triggers inflammation and cell damage, a condition now called metabolic dysfunction-associated steatohepatitis (MASH), some people develop pain or tenderness in the upper right abdomen along with fatigue. The pain tends to be a dull, persistent ache rather than a sharp sensation. Risk factors include carrying extra weight, having insulin resistance or type 2 diabetes, and high triglycerides.
What makes fatty liver disease tricky is that it can progress quietly. By the time pain becomes noticeable, the liver may already be significantly inflamed. That inflammation, left unchecked, can eventually lead to scarring and cirrhosis.
Alcohol-Related Liver Damage
Heavy or prolonged alcohol use inflames liver tissue directly, producing a condition called alcoholic hepatitis. The hallmark is tenderness and pain in the upper right abdomen, sometimes accompanied by fever, nausea, and jaundice (yellowing of the skin and eyes). The pain can range from mild soreness to sharp tenderness that worsens when the area is pressed. Because gallstones and infections can cause similar symptoms, it’s important to get the actual cause identified rather than assuming alcohol is to blame.
Alcoholic hepatitis can develop after years of heavy drinking, but it can also flare after a period of particularly intense consumption. Stopping alcohol use is the single most important factor in whether the liver recovers or continues toward permanent scarring.
Viral Hepatitis
Hepatitis A, B, and C all inflame the liver and can produce abdominal pain, nausea, dark urine, fatigue, fever, and joint pain. Acute infections, particularly hepatitis A, tend to cause more noticeable symptoms. Chronic hepatitis B and C often develop so slowly that many people are unaware of their infection for years or even decades. The CDC notes that symptoms of chronic viral hepatitis can take decades to appear, and when they do, they typically mirror those of the acute form: upper abdominal pain, fatigue, and jaundice.
If you have unexplained right-sided abdominal pain combined with fatigue or yellowing skin, a simple blood test can check for active hepatitis infection.
Liver Cysts and Growths
Fluid-filled cysts and benign growths called hemangiomas are common in the liver and usually cause no problems. Pain typically starts only when they grow large enough to stretch the liver capsule or compress nearby structures. Hemangiomas that reach 10 centimeters or more (roughly the size of a grapefruit) are classified as “giant” and are the most likely to cause symptoms, usually from swelling or compression of the stomach. Smaller cysts and growths found incidentally on imaging rarely need treatment.
Cancerous tumors, whether originating in the liver or spreading there from another site, can also cause right upper abdominal pain as they grow. This pain sometimes comes with unintentional weight loss, loss of appetite, or a feeling of fullness after eating very little.
Liver Abscess
A liver abscess is a pocket of pus that forms inside the liver, typically from a bacterial infection. Symptoms include pain in the right upper abdomen (sometimes radiating to the right shoulder or lower right chest), fever with chills and night sweats, nausea, loss of appetite, and unexplained weight loss. Some people also notice clay-colored stools, dark urine, or jaundice. A liver abscess needs prompt treatment to drain the infection and prevent it from spreading.
Medication and Toxin Exposure
Certain medications can injure liver cells, and the most common culprit is acetaminophen (Tylenol) when taken in excessive amounts. What’s deceptive about acetaminophen toxicity is the timeline: patients are often symptom-free or have only mild nausea in the first hours after an overdose. Liver damage then develops over one to four days, potentially progressing to severe liver failure if untreated. The danger is real even with doses that don’t seem extreme, especially if you’re also drinking alcohol or taking multiple products that contain acetaminophen.
Other medications, herbal supplements, and industrial chemicals can also cause drug-induced liver injury. The pain pattern is similar to hepatitis: a dull ache in the upper right abdomen, often accompanied by fatigue and sometimes jaundice.
Cirrhosis and Advanced Liver Disease
Cirrhosis is the end result of long-term liver damage from any cause. Scar tissue replaces healthy liver tissue, stiffening the organ and disrupting blood flow through it. Pain is common at this stage. In a 2025 cross-sectional survey of 118 adults with cirrhosis, 83% reported abdominal pain. Pain interference with daily activities was moderate to significant, affecting walking, general activity, and sleep at similar levels. The study also found that pain intensity correlated with disease severity: people with more advanced cirrhosis reported worse pain.
Cirrhosis also causes complications that produce their own discomfort. Fluid buildup in the abdomen (ascites) creates a heavy, bloated feeling. Swelling in the legs adds to overall pain burden. Both ascites and leg swelling were independently associated with higher pain intensity in the survey data.
How Liver Pain Is Diagnosed
Because so many conditions produce similar right-upper-abdominal pain, diagnosis usually involves blood work and imaging. Blood tests check for liver enzyme levels, viral hepatitis markers, and overall liver function. For imaging, ultrasound is the standard first step. It has a positive predictive value of 98% and sensitivity between 65% and 95% for identifying liver tissue disease. Ultrasound is also the go-to for detecting bile duct blockages and evaluating the liver during acute hepatitis or suspected toxic injury.
If ultrasound findings are unclear or suggest something that needs closer evaluation, MRI provides superior detail. It outperforms both ultrasound and CT for diagnosing and grading fat accumulation in the liver, and it’s the most useful tool for evaluating bile duct obstructions. CT scans are highly specific for detecting moderate fatty liver (100% specificity, 82% sensitivity) and are valuable for staging cancers that involve the liver or bile ducts.
What the Pain Feels Like
Liver-related pain is most often a dull, steady ache or a sense of heaviness below the right ribs. It can feel like pressure or fullness rather than a sharp, stabbing pain. Some people describe it as soreness that worsens when they press on the area or bend forward. Referred pain to the right shoulder blade or lower right chest sometimes occurs, especially with abscesses or large growths. If the pain is sudden, severe, and accompanied by fever or jaundice, that pattern points toward something that needs urgent evaluation, such as an abscess, acute hepatitis, or a bile duct blockage rather than a slower-developing condition like fatty liver or early cirrhosis.
