What is the cause of back swelling?

The most common cause of back swelling is muscle strain, myofasciitis, degenerative change of vertebral body, and hyperosteogeny. The treatment method is mainly to rest, reduce the local irritation, never get cold, and insist on applying hot water bags or salt bags for hot compress locally every day. In combination with physical therapy such as acupuncture, electric heating, cupping, massage and so on, some plasters can also be used externally to promote blood circulation and remove blood stasis, such as Huoxue Zhitong Plaster, which will gradually recover.
