I like to use light warm-up sets to help determine if my back will benefit from work or more rest. If you feel better as you warm-up, continue on and then based on how everything feels, you can decide if you want to do the program or just stick with some conservative weights. If you feel progressively worse as you warm-up, best to call it a day.
Rushing out to the doctor at the first sign of back pain is a waste of time IMO. It sucks, but you might need to learn through experience how your back reacts to different stimuli. Then you will be able to fine-tune your activity and recovery to keep the pain at a manageable level.
