I have stage 3 emphysema with a recent pulmonary function test showing lung function at 41%. I have been scheduled for shoulder surgery on Tuesday Nov 27th. I was told last week that it's considered a moderate risk having this surgery but without it my right arm is pretty much useless. I'm looking at pros and cons of anesthesia and would like to know if this would be wise or should I go with a local. Stressing over this after reading many articles. Any help would be great.
