Lumbar disc herniation and pyogenic muscle syndrome can coexist. Lumbar disc herniation is manifested by lumbar pain with leg pain and also with lateral lower limb pain. In the process of examination, a herniated lumbar disc is found to be herniated on the left side, while the pain of pear-shaped muscle syndrome is on the right side, which is better distinguished. A herniated lumbar disc that is compressed bilaterally or is compressed on the same side as the pear-shaped muscle syndrome is not easy to distinguish and requires caution in the choice of surgery. A herniated lumbar disc is one in which the entire medullary ring of the lumbar disc ruptures and protrudes posteriorly to compress the nerve roots. The pear-shaped muscle syndrome refers to the thickening of the pear-shaped muscle, and the sciatic nerve comes out of the mouth of the pear-shaped muscle and branches more to compress the sciatic nerve, resulting in pain below. In the treatment, measures and methods are needed to judge the situation before treatment.
