Hi My father is suffering the last phases of congestive heart failure - he has severe fluid build up in the abdomen and legs, he is breathless presumably due to fluid in the lungs, his kidneys are not tolerant of diuretics though the doctor has prescribed a stronger type. He already suffers for vascular dementia as a consequence of a heart attack over a year ago now. He is rarely awake and according to my mother constantly muttering. i m concerned about the amount of pain he may be in as it is clear he is not going to recover but would like to think we could minimise the discomfort. Can you advise me.
