Vitamin D as an Analgesic for Patients With Type 2 Diabetes and Neuropathic Pain

T reatment of neuropathic pain is generally unsatisfying for patients with type 2 diabetes mellitus, and patients with debilitating residual symptoms may be given nonspecific diagnoses such as “chronic pain syndrome.” Although hypovitaminosis D is highly prevalent in patients with type 2 diabetes, to our knowledge, its impact on neuropathic pain has not been previously evaluated. Our objective was to evaluate the impact of vitamin D repletion on neuropathic pain in patients with type 2 diabetes and vitamin D insufficiency.
