Back pain

Back pain can be caused by a wide variety of factors. Most lower back pain is triggered by some combination of overuse, muscle strain, and injury to the muscles, ligaments, and discs that support the spine. 

Acute pain from muscle strains or sprains is often relieved with rest. If an episode of low back pain lasts for more than two weeks, over time muscle strain can lead to an overall imbalance in the spinal structure. After straining muscles, you are likely to walk or move in different ways to avoid pain or to use muscles that aren't sore. That can cause you to strain other muscles that don't usually move that way. This condition make the back more prone to re-injury and have chronic low back pain. 

Acupuncture treatment is every effective for both acute and chronic lower back pain. Acupuncture can regulating the  blood circulation, relax muscle to promote the repairing of tissue. And at same time, acupuncture can increase the release of chemicals--endorphins to stop the pain.
