What causes calf muscle pain?

Calf muscle pain may be caused by trauma, lumbar spine disorders, or other factors. Localized tenderness in the calf muscles could result from local tissue edema or muscle pain during ankle joint movement. It might also be due to lumbar disc herniation, spinal stenosis, spondylolisthesis, or similar conditions, in which protruding intervertebral discs or overgrown joint capsules compress nerve roots, leading to calf muscle pain.
