Hello ! I read your question and understand your concern. There are some metabolic disorders you should exclude. These are a possible hypocalcemia ( low plasma level of Calcium) and thyoroid gland dysfunction. These two disorders can cause similar symptoms . I would recommend to do a blood test for calcium levels and thyroid hormones. If these two analysis result normal I would think about a psychiatric problem. The reaction of your wife to the situation is another argument in favor of this diagnosis. I would recommend a psychiatric evaluation for a conversion disorder. Hope to have been helpful! Best wishes ! Dr. Abaz Quka
