Experiment a dull but sharp pain in upper left back after smoking. No cough or sputum, or respiratory distress or headache. It is not a disc or a muscle. The x-ray was negative. Today I quit smoking. Could you please give some advice?

It usually happens when smoking or just after having left. You may have some swelling, infection or fluid behind the lungs. Should I just disappear, especially if radiographs came out with negative result. But anyway check with your doctor, especially if it lasts more than a couple of days.
