Problems affecting the right kidney, such as stones or infections, may cause pain in the right flank. Fever or changes in urination can appear at the same time.
Liver conditions like hepatitis may lead to pain in the upper right abdomen along with fatigue, loss of appetite, or yellowing of the skin and eyes.
Chest and heart related discomfort
In some cases, heart conditions can cause pain that spreads toward the right side of the chest. Lung infections such as pneumonia may also create right side chest pain, sometimes confused with heart or stomach issues.
Sudden pain versus long term pain
Sudden sharp pain often signals a condition that needs urgent medical attention. Persistent pain that lasts for weeks may relate to arthritis, nerve problems, or long term digestive disorders and should be evaluated by a doctor.
How doctors find the cause
A medical exam is usually the first step. Blood tests can reveal infection or inflammation. Ultrasound scans check the gallbladder, liver, and kidneys. CT scans or X rays may be used to examine internal organs and bones.
