About 7 months ago I had a collapsed left lung with chest tube and surgery. Burst bleb. Every time I cough or sneeze I feel pain in left lung. Why?
Inflammation. Make sure you dont have a recurrent partial collapse. If not you may have inflammation of the pleural cavity or irritation of some of the nerves along your ribs on that side. You may need a course of anti inflammatory medications ir evaluation by a pain specialist as you shouldnt have pain this late. Discuss with your surgeon.
