You can move your workouts to another form of activity.

Trade the treadmill for the elliptical trainer
If you are currently suffering from back pain, or have in the past, it might be a very smart choice to move your cardio workouts from the treadmill to the elliptical trainer. While running certainly is a good cardiovascular exercise and great for fat burning, it does contribute to a lot of impact on your vertebra.

If you really do have a great love of running and hate to give it up, at least consider cutting back on the volume you are doing. You really only need a couple of runs each week to keep yourself physically fit, and from there you can move your workouts to another form of activity.
