Dry beriberi at the pain clinic – B1 deficiency neuropathic pain post gastric bypass

Abstract

Neuropathic pain is associated with hyperalgesia, allodynia, and other paresthesia affecting the sleep, social, personal, and emotional life of a person. Numerous causes have been described for neuropathic pain. Nutritional deficiency is one uncommon cause. In this case report, we present a 27-year-old female patient who came to the pain clinic with severe burning pain, pricking sensation, and increased sensitivity to touch and pain for the past 2 months. The patient was diagnosed with thiamine deficiency and started on nutritional replacement therapy. A multidisciplinary approach involving drugs, physiotherapy along with replacement therapy was started, following which the patient started showing improvement in the symptoms.
