Hi , this is my first time of posting on here. 
My husband was diagnosed with stage 3 lung cancer back in November last year. Due to him having heart problems as well it was December before they were able to do a biopsy, which unfortunately was not successful, so another biopsy was done on his adrenal gland instead in February this year, we got the results last week that the cancer has spread and is now stage 4. My husband is now waiting to see a cancer specialist, but he is shrinking before my eyes , he has days where he has no interest in food, if I am lucky he may eat a yogurt and on the odd day he will eat a little more, he spends most of the day asleep and is in a great deal of pain in his shoulder, neck and back. The doctor told me to give him paracetamol, but I just don't know how to help him, he can't sleep as the pain is bad and when he does he has started shouting out in his sleep, does anyone have any experience of anything I can do which would help him? Thank you
