My husband has been suffering from pain in his back, hands, feet, and legs to the past 15 months. He has had numerous neurological work ups at different facilities that all came back normal. He has been to the Mayo clinic three times. He has seen a cardiologist rheumatologist, pulmonary specialist, 3 neurologists, and a doctor in infectious disease. His condition is progressively worsening and at this point we have no answers. We are open to checking into any and everything so please share if you have any insight for us.
