In this article, we’ll break down the common causes of pain on the left and right sides of the body, what symptoms to watch for, and when it’s time to see a doctor.

Left Side Pain

Pain on the left side of your abdomen or torso can stem from digestive organs, muscles, kidneys, or even the heart and lungs. It is generally categorized into upper and lower left pain.

Lower Left Pain

The most common cause of lower left abdominal pain is diverticulitis, an inflammation or infection of small pouches (diverticula) in the colon. It often presents with cramping, fever, and changes in bowel habits.

Other potential causes include:

• Irritable Bowel Syndrome (IBS) – Chronic digestive discomfort, bloating, and altered bowel movements.

• Constipation or gas – A build-up of waste or trapped air can cause noticeable pain.

• Gynecological conditions in women, such as ovarian cysts or ectopic pregnancy.

Upper Left Pain

Upper left abdominal or side pain can involve more serious conditions:

• Pancreatitis – Inflammation of the pancreas, often with nausea, vomiting, and radiating pain to the back.

• Gastritis or Stomach Ulcers – These can cause burning or gnawing pain, especially after meals.

• Enlarged Spleen – Often due to infection or immune-related diseases.

• Kidney infections or stones – May cause flank pain, fever, or painful urination.

• Heart issues – Conditions like angina or pericarditis can cause pain that radiates to the left chest and side.

• Pneumonia or pleurisy on the left lung can also mimic abdominal pain.

Right Side Pain

Pain on the right side of the body is also divided into upper and lower regions, each with distinct potential causes.

Lower Right Pain

One of the most well-known and urgent causes of lower right abdominal pain is appendicitis. This condition causes sharp pain that typically starts near the navel and moves to the lower right side. It often includes fever, nausea, and tenderness. Appendicitis requires immediate medical attention.

Other causes:

• Ovarian cysts or torsion

• Hernias

• Urinary tract infections

Upper Right Pain

This region houses several vital organs, including the liver, gallbladder, and part of the small intestine.

Common causes include:

• Gallstones or cholecystitis – Pain after eating, especially fatty foods, often radiating to the right shoulder.

• Liver conditions such as hepatitis or even liver cancer.

• Right kidney infections or stones

• Duodenal ulcers – Sores in the upper portion of the small intestine can trigger sharp or burning pain.

• Lung infections or rib injuries on the right side may also cause pain that worsens with breathing.

When to See a Doctor

While mild or temporary side pain may resolve on its own, it’s important to know when to seek medical help.

Consult a doctor if the pain is:

• Severe or persistent

• Recurring regularly

• Worsened by movement or meals

• Accompanied by alarming symptoms such as:

  • Vomiting or diarrhea

  • Blood in stool or vomit

  • High fever or chills

  • Difficulty breathing

  • Jaundice (yellowing of the skin or eyes)

  • Dizziness or fainting

  • Pregnancy

  • Unexplained weight loss

Seek Emergency Care If:

• The pain comes on suddenly and severely

• It intensifies rapidly

• You are unable to stand, walk, or breathe comfortably

• The pain is paired with chest tightness, which may signal a heart problem
