Pain on the Right Side of Abdomen: Causes, Symptoms and Warning Signs

Medically reviewed by Dr. Pankaj Agarwal, General Surgeon, CBLM Holy Family Hospital, Jaipur

Pain on the right side of the abdomen can come from the gallbladder, appendix, kidney, bowel, abdominal muscles or reproductive organs. Upper-right pain commonly involves the gallbladder or liver, while lower-right pain may involve the appendix, bowel, urinary tract or ovary.

Location offers useful clues, but the symptoms and a medical examination are needed to identify the cause. This guide covers what each region of the right side can point to, which symptoms mean you should stop reading and get to a hospital, and what a proper assessment involves.

When Is Right-Side Abdominal Pain an Emergency?

Most right-sided abdominal pain is not dangerous. A small share of it is, and the difference is decided by the symptoms sitting alongside the pain, not by the pain alone.

Arrange Urgent, Same-Day Assessment

Seek medical advice the same day for:

1. possible pregnancy with one-sided pain or vaginal bleeding, even without a positive home pregnancy test;
2. pain that is worsening, does not go away or moves towards the lower-right abdomen;
3. yellow eyes or skin, dark urine or unusually pale stools; or
4. pain with fever, urinary symptoms or recurrent vomiting.

Where Exactly Is the Pain?

Doctors describe abdominal pain by region, because the organs sitting in each one barely move. The list below shows possible sources, not a way to diagnose the problem at home.

Pain also travels. A gallbladder problem may be felt in the back or shoulder, while a kidney stone may move from the flank towards the groin. Pregnancy, previous surgery and natural differences in anatomy can all change where pain is felt, which is why location narrows the list without ever settling it.

Causes of Pain Under the Right Ribs

Gallstones and Gallbladder Inflammation

Gallbladder pain is usually felt under the right ribs or in the upper middle abdomen. It may build after a meal, remain steady for a time and spread to the back or right shoulder blade. Nausea or vomiting can occur.

Symptoms alone cannot show whether the problem is a temporary blockage, gallbladder inflammation or something else. Pain that does not settle, particularly with fever, repeated vomiting or increasing tenderness, needs prompt assessment. Yellow eyes or skin, dark urine or pale stools may point to a blocked bile duct and should be assessed urgently. Where stones are confirmed, treatment is usually gallbladder stone surgery.

Liver and Bile-Duct Conditions

Inflammation, infection or swelling of the liver can cause an ache or sense of heaviness beneath the right ribs, often alongside tiredness, poor appetite, nausea, fever or jaundice. Many liver conditions cause little or no pain at first, so pain intensity is not a reliable measure of seriousness.

Amoebic liver abscess is another condition clinicians may consider in India. It can cause persistent upper-right pain and fever, sometimes with discomfort near the right shoulder. Those symptoms overlap with several other illnesses, so diagnosis requires medical assessment and usually blood tests and imaging.

Lung, Rib and Muscle Pain

The bottom of the right lung sits just above the diaphragm. Pneumonia or inflammation around the lung can occasionally be felt as upper abdominal pain, especially when there is cough, fever or pain on taking a deep breath.

A bruised rib or strained abdominal muscle may hurt more with twisting, lifting or coughing. Even when the pain seems muscular, seek care if it is severe, follows an injury, or occurs with breathlessness, fever or other warning signs.

Causes of Lower-Right Abdominal Pain

Appendicitis

Appendicitis often begins with discomfort near the centre of the abdomen and later becomes more noticeable on the lower right. The pain commonly worsens over several hours and may come with loss of appetite, nausea, vomiting or fever. Walking, coughing or movement can make it more uncomfortable.

That familiar pattern is not present in everyone. Children, older adults and pregnant people may have milder pain, slower changes or pain in a different place. Do not rely on pressing the abdomen or checking a particular point yourself. Pain that is worsening, persistent or moving towards the lower right needs urgent medical assessment.

There is no safe number of hours to wait for suspected appendicitis, and a brief improvement does not prove the problem has passed. When appendicitis is confirmed, appendix surgery is usually carried out without delay.

Bowel-Related Causes

Gas and constipation can cause cramping, pressure or a sense of fullness on the right. Gastroenteritis may bring abdominal cramps, loose stools and vomiting. Irritable bowel syndrome can also cause recurring pain with changes in bowel habits.

These common problems can resemble more urgent conditions. Arrange an examination if pain is localised or worsening, keeps returning, wakes you from sleep, or occurs with fever, vomiting, bleeding, abdominal swelling or unexplained weight loss.

In India, clinicians may also consider abdominal tuberculosis when ongoing abdominal symptoms occur with fever, loss of appetite, weight loss, chronic diarrhoea, swelling or signs of bowel obstruction. Symptoms alone cannot confirm TB; proper testing is essential.

Hernia

A hernia may appear as a soft swelling in the groin or abdominal wall, often becoming more visible when standing, coughing or straining. A bulge that suddenly becomes painful, firm or stuck, particularly with vomiting or abdominal swelling, can mean bowel is trapped. That is an emergency. Do not repeatedly press or force a painful bulge back in. Stable hernias are assessed and repaired through planned hernia treatment.

Kidney and Urinary Causes

A stone in the right ureter can cause intense pain beginning in the side or back and travelling towards the lower abdomen or groin, rising and falling in waves. Nausea, vomiting, urinary urgency or blood in the urine can occur. Larger or obstructing stones may need kidney stone surgery.

People with renal colic are often restless, but behaviour alone cannot identify a kidney stone. Similar symptoms arise from several other conditions.

Fever or chills with suspected stone pain requires immediate care, because infection behind a urinary blockage can become dangerous quickly. Seek prompt help as well if urine output falls, pain remains uncontrolled, the person has one functioning kidney, or pregnancy is possible.

A kidney infection may cause flank or back pain with fever, chills, nausea and urinary symptoms such as burning or frequent urination. Seek same-day medical care. Emergency assessment is needed if the person is pregnant, confused, repeatedly vomiting, unable to keep fluids down or becoming seriously unwell.

Right-Sided Abdominal Pain in Women

Pain in the lower right abdomen may come from the ovary or fallopian tube, but bowel and urinary causes remain possible too. If pregnancy is possible, take a pregnancy test and tell the clinician, even when contraception was used. Do not wait for a positive home test before seeking care when one-sided pain occurs with bleeding or other concerning symptoms.

Ectopic Pregnancy

An ectopic pregnancy develops outside the uterus, most often in a fallopian tube. Possible symptoms include one-sided lower abdominal or pelvic pain and bleeding that differs from a usual period. Sudden severe pain, shoulder-tip pain, weakness, dizziness or fainting may indicate internal bleeding and requires emergency care, which may involve laparoscopic surgery for ectopic pregnancy.

Ovarian Torsion

Ovarian torsion happens when an ovary twists and its blood supply is threatened. It often causes sudden one-sided pain with nausea or vomiting, though the pain may be intermittent. It is a surgical emergency and cannot be confirmed or excluded through a home test.

Ovulation Pain, Cysts and Endometriosis

Ovulation can cause one-sided discomfort around the middle of a menstrual cycle. Ovarian cysts may cause pressure, aching or sudden pain if they bleed or rupture, and persistent or large cysts are sometimes treated with ovarian cystectomy surgery. Endometriosis may cause pain that repeatedly worsens around menstruation, sometimes with painful sex or difficulty conceiving.

Cycle timing can provide a clue, but it should never be used to dismiss severe, new or persistent pain. Urgent conditions must be excluded first.

Other Conditions That Can Feel Like Abdominal Pain

Some causes begin outside the abdominal organs entirely:

1. Shingles may cause burning or sensitive skin on one side before a rash appears.
2. Abdominal-wall pain can follow lifting, exercise, coughing or a minor injury.
3. Nerve irritation may create a small, sharply tender area in the abdominal wall.

Because symptoms overlap, a single clue, whether that is where the pain sits, how it changes with movement or how someone behaves, should not be treated as proof of a diagnosis.

What Happens During a Medical Assessment

The clinician will usually ask where the pain began, whether it moved, how it has changed, and whether there is fever, vomiting, bowel trouble, urinary symptoms, bleeding or a chance of pregnancy. They will check vital signs and examine the abdomen gently.

Depending on the findings, tests may include:

1. blood tests for infection, anaemia, liver function or kidney function;
2. a urine test for infection or blood;
3. a pregnancy test when pregnancy is possible; and
4. imaging such as ultrasound, CT or MRI.

The choice and order of scans depend on the person's age, pregnancy status, examination and the condition being considered. Sometimes observation and repeat examination are useful, because abdominal symptoms evolve. No single test identifies every cause of right-sided pain. Where surgery is needed, many of these conditions can be treated through laparoscopic surgery.

What to Do While Arranging Care

Pain relief does not prevent doctors from assessing abdominal pain. The safest choice depends on pregnancy, allergies, ulcers, kidney or liver disease, blood-thinning medicines and other factors. If unsure, ask a doctor or pharmacist and follow the labelled dose. Do not delay urgent care simply to complete a period of fasting.

When Symptoms May Be Less Typical

Young children, older adults, pregnant people, those with long-standing diabetes-related nerve damage, and people with a weakened immune system may not develop the expected fever or pain pattern. A change in behaviour, unusual drowsiness, poor feeding, confusion or a general sense that the person is becoming more unwell can matter even when the pain sounds mild.
