Hi Anon,

Thanks for posting. There are many reasons why you may be feeling pain on your left side--

Causes of upper left abdominal pain include:

Angina (reduced blood flow to the heart)
Cancer
Diverticulitis
Empyema (infection of the lining around the lungs)
Enlarged spleen (splenomegaly)
Fecal impaction (hardened stool that can't be eliminated)
Gastritis (inflammation of the stomach lining)
Heart attack
Hiatal hernia
Injury
Kidney infection
Kidney stones
Pancreatitis (pancreas inflammation)
Pneumonia
Pulmonary infarction (loss of blood flow to the lungs)
Pyloric stenosis (in infants)
Ruptured spleen
Shingles
Spleen infection
Splenic abscess (pus-filled pocket in the spleen)
Thoracic aortic aneurysm
Torn colon

If something is inflamed, then this could be why it hurts upon breathing-- since you may be causing a rub. Visiting your doctor and pinpointing exactly where it hurts may help diagnose and treat you. Unfortunately, we can only give you possibilities. Hope the list helps!
