Low back pain alone does not cause a low-grade fever, and among the causes of illnesses that lead to low back pain is the possibility that they do cause the body to develop a low-grade fever. For example, infectious diseases can trigger low back pain, which can then lead to a fever. For example, tuberculosis of the lumbar spine as well as low back disorders due to bacterial infections can cause low back pain along with a low-grade fever. The vast majority of conditions that cause low back pain do not cause a low-grade fever, including common conditions such as lumbar disc herniation, lumbar strain, lumbar spondylolisthesis, and lumbar spinal stenosis.
