Pain under the right rib is a surprisingly common complaint that affects people of all ages and backgrounds. Because this area houses several vital organs — including the liver, gallbladder, and parts of the intestine — the discomfort can signal anything from a pulled muscle to a condition that needs urgent attention. Understanding the possible causes can help you have a more informed conversation with your doctor.
1. Gallstones
Gallstones are hardened deposits of digestive fluid that form inside the gallbladder. They are one of the most frequent reasons people experience sharp pain under the right rib. The discomfort often strikes after eating a fatty meal. It can last from minutes to several hours and may radiate to the right shoulder or back. Research suggests that women, people over 40, and those with a family history face higher risk. According to Medical News Today, gallbladder issues rank among the leading causes of right upper quadrant pain. If you notice recurring episodes, schedule an appointment with your healthcare provider for an ultrasound evaluation.
2. Liver Inflammation
The liver sits directly beneath the right ribcage, so inflammation here often causes a dull, persistent ache in that area. Hepatitis, fatty liver disease, and excessive alcohol consumption can all trigger liver inflammation. Some people also notice fatigue, nausea, or yellowing of the skin. Clinical evidence shows that non-alcoholic fatty liver disease now affects roughly one in four adults worldwide. Early detection matters because the liver has remarkable healing ability when the underlying cause is addressed. Reducing alcohol intake, managing weight, and eating a balanced diet are practical first steps worth discussing with your doctor.
3. Costochondritis
Costochondritis is inflammation of the cartilage connecting your ribs to the breastbone. It can create a sharp, stabbing pain that mimics more serious conditions. The discomfort typically worsens with deep breathing, coughing, or physical movement. While it often resolves on its own within weeks, it can be alarming when it first appears. Studies indicate that costochondritis accounts for a notable share of chest pain visits to emergency rooms. Applying a warm compress and avoiding activities that aggravate the area may help ease symptoms while you recover.
4. Slipping Rib Syndrome
This underdiagnosed condition occurs when one or more of the lower ribs shift out of their normal position. The movement can irritate surrounding nerves and cause a burning or clicking sensation. Research from NIH/PMC characterizes slipping rib syndrome as burning pain in the lower thorax and upper abdomen caused by hypermobility of costal cartilage with intercostal nerve entrapment. It is frequently mistaken for gallbladder or gastrointestinal problems. A clinical review of 76 cases published in PubMed defined the syndrome by three features: lower chest or upper abdominal pain, a tender costal margin spot, and pain reproduction on palpation. If your pain worsens with twisting or bending, ask your provider about this possibility.
5. Kidney Issues
The right kidney sits just behind the lower ribs toward the back. Kidney stones, infections, or inflammation can produce pain that wraps around to the front of the ribcage. This type of discomfort often comes in waves and may be accompanied by changes in urination. You might also notice fever or blood in urine if an infection is present. Studies suggest that staying well hydrated is one of the most effective ways to reduce kidney stone risk. Seek prompt medical attention if the pain is severe or you develop a high fever.
6. Muscle Strain
Sometimes the simplest explanation is the right one. Overexertion during exercise, heavy lifting, or even a prolonged coughing spell can strain the intercostal muscles between the ribs. The pain usually feels worse with movement and tender to the touch. Rest, gentle stretching, and over-the-counter anti-inflammatory medication often provide relief. Research from NIH/PMC explains that problems with interchondral fibrous attachments can cause costal cartilage subluxation and nerve impingement, creating pain that closely mimics organ-related conditions. If your symptoms began after physical activity, muscle strain is a likely culprit worth mentioning to your doctor.
7. Irritable Bowel Syndrome
IBS is a chronic digestive disorder that can cause discomfort almost anywhere in the abdomen, including under the right rib. Bloating, gas, and irregular bowel habits often accompany the pain. Stress and certain foods tend to make flare-ups worse. Clinical evidence shows that IBS affects between 10 and 15 percent of the global population. The condition is functional, meaning tests often come back normal even though the pain is very real. Keeping a food diary to identify triggers and practicing stress management techniques are two practical strategies that research supports.
8. Pneumonia or Pleurisy
Infections in the right lung can produce pain that feels like it originates under the ribcage. Pneumonia causes inflammation deep in the lung tissue, while pleurisy inflames the membrane surrounding the lungs. Both conditions typically worsen with breathing. Cough, fever, and shortness of breath are common accompanying symptoms. Studies indicate that right lower lobe pneumonia is sometimes initially misdiagnosed as an abdominal problem because the pain can feel so localized. If you have rib pain along with respiratory symptoms, seek medical evaluation promptly.
9. Peptic Ulcer
A peptic ulcer is an open sore on the lining of the stomach or upper small intestine. When it develops on the right side, the gnawing or burning pain can radiate beneath the right rib. Eating may temporarily relieve or worsen the discomfort depending on the ulcer’s location. Helicobacter pylori infection and long-term use of nonsteroidal anti-inflammatory drugs are the two most common causes. Research suggests that effective treatment often involves a combination of antibiotics and acid-reducing medications. Avoiding spicy foods, alcohol, and smoking may help manage symptoms while you pursue a diagnosis.
10. Appendicitis
While appendicitis pain classically begins near the navel and moves to the lower right abdomen, some people experience discomfort that extends higher toward the right rib area. This is especially true in pregnant women or individuals with an unusually positioned appendix. The pain tends to escalate quickly over 12 to 24 hours. Nausea, vomiting, fever, and loss of appetite are common warning signs. Clinical evidence shows that early surgical intervention dramatically reduces the risk of complications like rupture. If you develop sudden, intensifying right-sided pain with these symptoms, seek emergency care immediately.
Pain under the right rib can have many explanations, ranging from a simple muscle strain to conditions that require prompt treatment. The key takeaway is to pay attention to accompanying symptoms, track how long the pain lasts, and consult a healthcare professional whenever the discomfort is persistent, severe, or worsening.
