Was hoping my husband s cardiologist would call us back. I need some advice on my husband s problem. One month ago he had a heart attack, Cath didn t work, due to veins to twisted. He is experiencing on and off pain on the left side of his forehead. Pretty regular and painful. His toes, on left foot are turning blue. Especially his big toe. I know this is a diabetic neuropathy problem, but we need to know if this is a serious situation or not. Yes, he is diabetic, but not on shots. This blue toe problem is new. So are the headaches. He refuses to go to emergency room. We are poor. I don t know what to do.
