--at least in the sense that a vitamin deficiency can make almost any dysfunction of peripheral nerves worse through lack of a proper regulatory/supporting atmosphere.

In general, compressive neuropathies, such as meralgia parasthetica (and many spinal radiculopathies) may become more noticable if one has an underlying toxic/metabolic condition (diabetes/imparied glucose tolerance being the best known, but also thyroid dysregulation, chemotherapeutic poisoning, and others). This is known as the "double crush phenomenon"--a nerve already compromised by less than ideal conditions may react to additional pressure in such a way as to make the symptoms much greater than the "sum of the parts" might be expected to be.
