I Have Chronic Back Pain After My Second Kids Birth.

I have chronic back pain after my second kids birth. I ended up delivering flat (due to some negligence) for my second baby and during delivery I sensed a distinct pain in my lower back. Its been 8 months post delivery but I feel the exact pain i felt during my delivery in the lower back. Gets very difficult for me to get up in the mornings from the bed. Massages give me a temporary relief. Is it possible to cure this by exercise.
