Pain on the right side can come from many different sources. Sometimes it is caused by a simple muscle strain. Other times it may point to an internal health issue. The discomfort can appear suddenly or develop slowly over time, and accompanying symptoms often help doctors identify the cause.

Muscle and posture related pain

Strained muscles or minor tears on the right side of the body are common after heavy lifting, sports, or repetitive movements. Back pain on the lower right side can also develop from poor posture, herniated discs, or pinched nerves. This type of pain may spread toward the hip or leg.

Digestive system causes

Appendicitis is one of the best known causes of sharp lower right abdominal pain. It often begins near the navel before settling on the right side and may come with fever, nausea, or vomiting.

Gallstones can trigger intense pain in the upper right abdomen, especially after eating. The discomfort may radiate to the back or shoulder.

Irritable bowel syndrome can also cause recurring right side abdominal pain, usually alongside bloating or changes in bowel habits.

Kidney and liver related pain
