When back pain occurs during walking, it is mainly due to strain, strain and cold in the vertical spinal muscles of the back, resulting in the formation of local sterile inflammatory lesions, and the inflammatory metabolites will stimulate the peripheral nerves and blood vessels, resulting in decreased blood supply and soreness. As the spine needs to maintain stability during walking, the muscles next to the spine become tense and contracted, which in this case stimulates the areas of strain, strain, and cold, resulting in significant pain when these lesions are stimulated. Usually after rest, hot compresses, warmth, pain symptoms can be significantly relieved, you can also warm water bags of hot compresses, 3-5 times a day, 20-30 minutes each time, can increase blood circulation, promote the absorption of inflammatory metabolites, can effectively reduce the pain. It is best to rest in bed after a strain, so that the strained part is in a relaxed state to help recovery.
