In the treatment, rest, rest and attention to warmth are the main focus. The patient can be instructed to sleep on a hard bed, reduce weight-bearing activities in the lumbar region, and avoid getting cold.

In the lumbar spine, acupuncture, moxibustion, iontophoresis of Chinese herbal medicine at acupuncture points or hot towel compresses, fumigation with osteopathic medicine, local closed injections, oral medication such as Shujianzhi and blood circulation tablets, Yunnan Baiyao, Bone Spur Pian tablets, and Dahuoluo Dan can also be used.
