Due to the amputation of my husband’s foot, we spent Christmas this past year in the Mayo Clinic hospital. This is the twelfth year of a long story.  David has had a pain in his left foot when he walked on it for the last 12 years.  Medical opinion assumed the problem was neurological.  He was referred to countless doctors who referred him for x-rays, CT and MRI scans.  No one could find anything to explain the pain.  One pain clinic installed a nerve stimulator in his back that was controlled by a technician at Abbot Labs who determined the dosage and the frequency of the nerve jolts.  It didn’t work!
