Vitamin D Deficiency Associ­ated with Neuropathic Pain

People with RA who suffer from neuro­pathic pain – or, understandably, are try­ing to avoid it – may do well to have their vitamin D levels checked. A study examined neuropathic pain indicators as well as blood samples of 93 patients with RA. The researchers found the prevalence of neuro­pathic pain was almost six times higher in patients with serum vitamin D levels below 20 nanograms per milliliter (ng/mL) than in patients with vitamin D levels ≥ 30 ng/mL. Anything below 20 ng/mL is considered a deficiency.
