Lower Back Spasm Causes. There are many reasons why muscle spasm may occur. Back injury is a very common factor, since inflammation and neurological trauma are both sources of severe muscular contractions. Usually, back muscle spasms due to injury will subside in a few hours to a few days. It is rare for spasms to last for weeks or months due to physical injury. Poor circulation to any area of the back is the most common source of spasm. This can occur due to structural concerns, such as vascular disease or inflammation, but typically is linked to a psychosomatic back pain syndrome using oxygen deprivation as the enforcer of a subconsciously devised distractive mechanism.
