Thank you, Ellen, for responding. John has been takin neurontin but it isn't working as of yet. You suggest taking calcium and magnesium. I've heard about taking vitamin B12 - so some things i can look into. I'm hoping it doesn't get worse. So far, he's not complaining that much. Just complains of being cold in the house. I know he has higher tolerance for discomfort than i do. He did say his handwriting has suffered.
