I had two thirds of my right lung removed 8 weeks ago. The best way to prevent pain the first 4 days is to have a morphine line right into your spinal cord. It sounds nasty but I was virtually pain free and when they removed it I didnt even feel it. After that I relied on pain meds for about 3 weeks to control the pain, but it did do the trick. I was worried that I would never be able to climb the stairs again because I was so out of breath, but this week (8 wks later), I feel great. I am almost back to normal. The doc says my other lung and the little piece of my right lung will stretch and take over and I believe it has. It is not such a bad operation, I hope this helps.
