Based on the scenario above, since the electrocardiogram revealed nothing unusual and indicate the she’s not having a heart attack, the pain the she may be experiencing every time she took a breath is pleurisy. Pleurisy is a condition in which this occurs when the pleura or the membrane the consist of the layer of tissue that is inlined with the inner side of an individual’s chest cavity and layer of tissue that surrounds the lungs has been inflamed or swollen in which will make an individual experience symptoms such as having sharp pain in the chest and that it would usually worsen when the individual is breathing.
