The difference between lumbar disc herniation and lumbar muscle strain pain is as follows: 1. Lumbar disc herniation: lesions in the spinal canal, compressing the nerves in the spinal canal and cauda equina, manifesting as soreness, pain, numbness and weakness in the lower limbs; 2. Lumbar muscle strain: lesions in the lumbar spine paravertebral, mainly in the soft tissues of the lumbar spine outside the spinal canal, such as: muscles, ligaments, fascia, etc. Most of the long-term overexertion leads to strain changes, manifested as lumbar soreness, swelling and discomfort. If you sit or stand for a long time, you will feel soreness and pain in your lower back.
