Hello. I m Dr. Christensen. I m sorry you re uncomfortable. While your chest cramps could be due to a benign but painful condition like viral pleuritis (also known as pleurisy), these symptoms could also be caused by something more serious such as pulmonary emboli (blood clots in the lung), a lung tumor, or a spontaneous pneumothorax (a partially collapsed lung). I d suggest you see your doctor or go to an urgent care center as soon as possible. Once the serious problems are ruled out, an over-the-counter anti-inflammatory medication should take the edge off your pain until the condition clears. However, a large pulmonary embolism can be fatal, so it s important to make sure you re not dealing with a serious condition before you try treating this on your own. I hope that helps, and I hope things go well!
