Hi Lisalou, Cookiegirl hasn't been on the site since the day after her last post; I suspect her dad died within a few days as he was clearly in the very final stages of the disease.
I am sorry that your father-in-law has now been diagnosed with small cell; as you have obviously realised, it is a dreadful version because it is so hard to treat and the end can be very quick, especially if it has gone to his lungs, liver or brain. Has he been referred to a hospice or Macmillan service? If not, you need to get that done asap as they will hopefully have day care, alternative therapies, support for your husband etc plus generally the hospice teams are far better at pain management than GPs or hospitals are. The hospice will also have a social worker who can advise you on how to apply for benefits for f-i-l, which he is now entitled to because he is terminally ill. This money is to help pay for any practical things he might need (such as hand rails, mobility scooter, etc) or to pay towards any care he might need.
