Lumbar pain may be caused by lumbar muscle strain, lumbar back fasciitis, transverse syndrome and other diseases. 1. Lumbar muscle strain: when chronic inflammatory lesions occur in the lumbar muscles and their attachment points of fascia or periosteum, it will stimulate the muscle fibers leading to spasms and twitching. 2 lumbar back fasciitis: long-term lumbar back fasciitis can lead to lumbar disc herniation, compression of nerves leading to lumbar pain, numbness and other symptoms, triggering lumbar special pain. 3. Transverse Syndrome: Improper exercise leads to transverse syndrome, which will cause the patient’s local muscle tissues to tear, causing pain, difficulty in movement and other symptoms, which in turn leads to lumbar pain. Lumbar pain may also be seen in rheumatoid, lumbar disc herniation and other diseases, if the symptoms of lumbar pain, persistent and unrelieved, need to consult a doctor in a timely manner to reduce the adverse effects of the disease.
