I am a full-time carer for my mother who has stage four heart failure and osteo-arthritis, is obese due to being unable to walk for the last three years and gets breathless and wheezy on any exertion. She takes her medication regularly but still gets swollen legs even with them elevated. Mentally she is alert but her hearing is poor even with aids. She is always uncomfortable, relies on analgesics throughout the day and I wonder how long she has to live like this. I do what I can for her but her quality of life seems so poor.
