How much pain is normal after a lung biopsy? i had a biopsy more than a week ago, and im still having pain. is this normal?

Variable: Generally, yes. The recovery greatly depends on the technique/s used. Vats? Thorocotomy? What is your body shape, i.e. How much space between your ribs? Often, deep breathing spirometer and stretching exercise under surgeon guidance helps. Your thoracic surgeon would be better able to discuss reasonable recovery expectations and what sort of activities may help or should be avoided.
