My husband is 70 yr old. He has for the last four months been weak and cold.he lies on the sofa all day covered with a blanket. He normally is very active and outside on some kind of project. He gets up in th morning and coughs until he commits. He either is constipaped or has diabetes for which he takes Imodium AD. His muscles ache and are weak . He overall just is not himself. He is worried he had triple bypass heart surgery four years ago. He is wearing a heart monitor because his rate is going to 143 sometimes. His no was down to 82/50. It has since improved. Any ideas on this one?
