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.
