As the lower back doesn't stay steady all the time, it is at high chance of getting injured due to accidents or while bending to pick up something. This may result into pain in the back. Back agony can also occur due to irritation in the nerves that connect the spine to the nervous system. Generally back pain is acute, caused by factors like strain to it or minor accidents and goes away in some days time. However, when the discomfort continues for a substantial period of time ( more than three months ), then it can be said that a person has lingering lower back trouble.
