pleurisy or pain that mimics
pleurisy, such as a pinched
nerveNerve biopsy
Nerve conduction velocity. Such pain can be caused by viral or bacterial infection, by
clotsBlood clots to the lung or by an injury to the chest wall, such as a fractured rib that can occur, sometimes, with just one hard cough. Bottom line, given the possibility that this could be the first sign of a serious problem, you should definitely go to your doctor or the nearest emergency room (ER) for an examination and a chest x-ray.
Good luck.
