Hello. I'm sorry you're uncomfortable. The type of pain you've described here is suggestive of pleurisy, which is caused by inflammation of the membranes surrounding your lungs and lining your chest cavity. Pleurisy can stem from a variety of causes, including viral infections, bacterial pneumonia
, chest wall injuries or pulmonary emboli
(blood clots in the lung).
Other possible causes of such pain include gallbladder
disease (the pain due to an inflamed gallbladder frequently "refers" to the right chest), intercostal neuralgia
(irritation of one or more of the nerves between your ribs), rib pathology (tumor, fracture, etc.) or costochondritis
(inflammation in the joints between your ribs and sternum).
Since your doctor examined you, I presume she didn't find any evidence of gallbladder disease. However, further investigation -- including gallbladder ultrasound, chest x-ray and possibly chest CT -- may be needed to diagnose your problem. I suggest you return to your physician to discuss the next step in your evaluation.
I hope that helps, and I hope you feel better soon!
