Whats "Comfortably Numb" about?

I thought it was appendicitis.

No, although playing almost the entire show (which Roger did in fact do, I have a recording of the specific night it happened on the Animals tour in Philadelphia) with a burst appendix would be quite impressive. It was hepatitis.

i'm gonna use references to the movie here. to me, comfortablt numb is about how pink's life has been lived so fast, with drugs and rock, along with losing his father and wife, have been eating away at him, and essentially he is mentally decomposing. but still, his power-hungry manager (movie reference here) is forcing him to keep on going. so pink has now become so withdrawn that he can no longer feel emotion, and life is passing him by. Oh, and sorry if this is considered dead, i just felt i had to post this.
