We have several people on WhatNext who are affected by pancreatic cancer, so I am sure someone will weigh in soon. In the meantime, I have reached out via social media to see if I can find someone who has shared this experience can give you some insight into how they have dealt with it.
Has your husband's health care team been able to give some advice or recommendations as to how he can be made more comfortable? Maybe they can make some suggestions, too.
Please know that we will do whatever we can to help.
