what is the cause of crackling under the skin around a chest tube site
Pulmonary Causes of Chest Pain. Pneumonia is an infection that develops in the lungs. It can lead to inflammation of the lung tissue or the tissue that surrounds the lung, a condition called pleuritis. Both conditions can cause chest pains. The pains of pneumonia and pleuritis are often made worse by deep breaths or coughing. A rare but life-threatening condition that affects the lungs is pulmonary embolism, a blood clot that develops in a vein in the pelvis or legs.
