Much of the success of getting back pain to stay away had to do with the conditioning and strength of your corset. This is the abdominal muscle and lower back muscle tone, condition, and strength. There is no pill or shot that will achieve this; only proper, appropriate exercises will help you achieve these goals. Keeping a decent weight, allowing your body to rest and recover after a workout, staying hydrated, doing thoughtful things with your body (as opposed to thoughtless or careless), and sleeping enough will also help get you pain free and stay pain free.
I hope this helps,
