Hi Hawaiigirl0906. I had most of my LUL removed in May and a RUL segmentectomy and RML wedge resection done in August. I started coughing 2 days post op with the second surgery. It's a dry cough. It has improved in intensity and frequency over the past three weeks but persists. I have tried the tessalon pearls but they have not helped. Oddly enough, I do not cough when I lay down flat. This helps with sleeping at night. I am hoping it's just temporary irritation to the airways from surgery and will go away in time. I would be interested if you learn anything that could be helpful.
