We present a case of a woman with a progressive hip and feet pain. Many biochemical, clinical, and radiological tests were performed for diagnosis. All were found to be normal. The patient was diagnosed as having RLS. 0.25 mg pramipexole was given for treatment. Patient symptoms patient escalated over six months. The patient was reassessed after six months. Vitamin D levels had not been previously examined. We found low vitamin D and calcium levels, as well as pseudofractures in radiography. The diagnosis was changed to osteomalacia. Vitamin D and calcium treatment were started. Symptoms began to regress from the first week of treatment
