Lower back pain can be caused by a range of troubles with any parts of the compound, interconnected network of spinal muscles, nerves, bones, discs or tendons in the lumbar spine. While lower back pain is really general, the symptoms and severity of lower back pain differ deeply. A easy lower back muscle strain might be excruciating sufficient to require an emergency room visit, while a degenerating disc might cause only mild, intermittent discomfort.
