Muscle strain. If you've been doing a lot of twisting or lifting, you may have strained a muscle.

Costochondritis. Inflammation of the cartilage connecting your ribs to your breastbone can cause sharp chest pain.

Spleen issues. An enlarged or ruptured spleen can cause pain and tenderness in the upper left abdomen.

Kidney infection or stones. Left-sided kidney pain is usually felt in the lower back, but can radiate to the front.

Pancreatitis. Inflammation of the pancreas can cause pain that radiates to the back.

Lower Left Abdominal Pain (Below the Belly Button)

Gas and constipation. This is the most common cause of lower left pain.

Diverticulitis. Inflammation of small pouches in the colon can cause sharp, cramping pain on the left side.

Irritable bowel syndrome (IBS). Cramping, bloating, and pain are common symptoms.

Ovarian cysts or issues. In women, ovarian cysts, ovarian torsion, or other gynecological issues can cause pain on the lower left side.

Kidney stones. Stones in the left ureter can cause sharp, cramping pain that comes in waves.

Left Chest Pain

Heart issues. Angina, heart attack, and other heart conditions can cause pain, pressure, or tightness in the left chest. Always take chest pain seriously.

Costochondritis. Inflammation of the rib cartilage is a common, harmless cause of sharp chest pain.

Pneumonia or pleurisy. Lung infections can cause pain that worsens with breathing.

Muscle strain. If you've been coughing a lot or doing heavy lifting, you may have strained a muscle.

When to Call a Doctor

Most left-sided pain is not an emergency. But you should see a doctor if:

The pain is severe or sudden. Sudden, sharp pain could be a sign of a kidney stone, diverticulitis, or other serious condition.

The pain is accompanied by fever. Fever with abdominal pain could indicate an infection.

The pain is accompanied by nausea or vomiting. This could be a sign of pancreatitis, gallbladder issues, or a kidney stone.

The pain is accompanied by blood in your stool or urine. This needs prompt evaluation.

You're pregnant. Always check with your doctor about new symptoms during pregnancy.

The pain is in your chest. Any chest pain, especially if it's accompanied by shortness of breath, sweating, or nausea, should be treated as a medical emergency.

The pain persists. If the pain doesn't go away after a few days of home care, see a doctor.

What to Do at Home

If your left-sided pain is mild and you don't have any alarming symptoms, you can try these home care strategies.

• Rest. Lie down and allow your body to relax.

• Apply heat. A heating pad or warm compress can help relax tense muscles.

• Drink clear fluids. Staying hydrated can help reduce digestive issues.

• Take over-the-counter pain relievers. If you don't have a contraindication, ibuprofen or acetaminophen can help.
