Bending over and feeling a pulling sensation in the lower back is usually caused by lumbar degenerative lesions, lumbar back myofasciitis, ankylosing spondylitis and other factors. 1. Degenerative lesions of the lumbar spine: for example, lumbar disc herniation can lead to nerve compression, thus making the lumbar pulling sensation as well as lower extremity numbness, pain and other symptoms. Lumbar vertebral osteophytes can also lead to compression of the neighboring nerves, causing muscle spasm in the lumbar back, resulting in the symptoms of pulling sensation. 2. Myofasciitis of the lower back: it is a sterile inflammation of the muscles of the lower back triggered by long-term muscle strain and exposure to cold and exertion. It can be manifested as pulling sensation, tightness and soreness in the lower back, which will be more obvious in the case of bending over. 3. Ankylosing spondylitis: a chronic inflammatory disease of the spine and sacroiliac joints. In the early stage, it can be manifested as lumbar pulling sensation and tightness. It is usually alleviated after activities. If there is a pulling sensation as well as a pulling sensation when bending at the waist, it is recommended to consult a doctor in time and standardize the treatment under the guidance of the doctor.
