with the development of lumbar disc degeneration and herniation
has been documented. Metabolic effects of active vitamin D metabolites in the nucleus pulposus and annulus
fibrosus cells have been studied. Lumbar disc herniation is a process that involves immune and inflammatory cells
and processes that are targets for immune regulatory actions of vitamin D as a neurosteroid hormone. In addition
to vitamin D’s immune modulatory properties, its receptors have been identified in skeletal muscles. It also affects
sensory neurons to modulate pain. In this study, we aim to study the role of vitamin D3 in discogenic pain and
related sensory deficits. Additionally, we will address how post-treatment 25-hydroxy vitamin D3 level influences
pain and sensory deficits severity. The cut-off value for serum 25-hydroxy vitamin D3 that would be efficacious in
improving pain and sensory deficits in lumbar disc herniation will also be studied
