Lumbar muscle strain lies in young or middle-aged people, often due to frequent sitting, or low activity of the muscles of the lower back, the relative weakness of the muscles caused by the muscle tension, spasm, pain in the aseptic inflammatory response. It can also be caused by minor trauma, such as mild strains, sprains, catching a cold, or being in one position for too long, resulting in muscle pain, often episodic. The pain can also be more intense when symptoms are severe, often requiring rest, topical creams or oral painkillers for treatment, and usually does not recur frequently. With age if the lumbar muscle strength is weak, the proliferation and degeneration of the bony joints of the lumbar spine will be accelerated, resulting in the relative instability of the lumbar spine. The degeneration of the lumbar spine will be localized aseptic inflammatory reaction, recurring symptoms of lumbar pain, so for lumbar muscle strain, early attention should be paid to more lumbar and dorsal muscle function exercise, enhance the lumbar and dorsal muscles, so that the lumbar vertebrae can be protected from repeated recurrence and old age lumbar degenerative osteoarthropathy.
