Does anyone know if mild to moderate emphysema can be very painful. Is it possible that there may be another? problem that the doctors have overlooked. Like mesothelioma becuase my father was a smoker for 40 years but also was exposed to asbestos for about 30 years working as a mechanic. Plus there is asbestos in the house he has lived in for 30 years. 

he has been to two doctors and both have said it is emphesema. 

he has not smoked in 2-3 years. his symtoms are stabbing pain in right side of chest, neck, and right arm that has been constant for three years. his cheeks and neck get hot. sensitivity to light. the main thing that worries me is the right arm and neck being included in the pain. if someone could tell me that this is normal we would both feel alot better. thanks
