And I got hunger pain that grow insane

from Kendrick Lamar – Swimming Pools (Drank) Lyrics 2 on Rap Genius

Kendrick’s playing off “appetite” from the previous line, but what he means here is that his desire for change is growing out of control. His appetite is causing pain.

He’s saying he’s tired of the same old shit and that he can’t take it anymore (hence the dependence on drugs that’s discussed later in the song)
