I would talk to DAN and get a second opinion from a doctor. You may want to consult a pulmonary doctor. With the injury and removal of part of your lung you may have an increased risk of obstructions, gas embolism, etc. Your issues might be bone related or with your lungs. The doctor has to know something about the physics and physiology of diving. It may be that your doctor did not understand the equal pressure that breathing compressed gas causes, as a previous message in this thread indicated.
