Hi everyone, odd situation, I'd be grateful of any advice. My dad in his 70s looks after an elderly gent (92) who lives round the corner from us. Initially it was just getting his shopping and providing a bit of company but now the gentleman is quiet reliant on my dad. Dad takes him to all his appointments since he was diagnosed with skin cancer and bowel cancer 2 years ago my dad helps out in all kinds of ways. His only relatives live further away and he doesnt have a great relationship with them anyway. Dad is now there at least once a day sometimes several times, he takes him hot meals, does all his cleaning, my dad is who he calls when he needs anything or in an emergency. The gentleman's catheter is problematic due to his tumour and the district nurses couldn't sort it out today so advised dad take him to hospital. The skin cancer (a patch on his head)which has tripled in since a fortnight ago is oozing and has matted his hair, and the district nurses havent cleaned it up since it ruptured 3 days ago. He got sent home from.hospital tonight and is hugely wobbly on his feet. My question is at what point do you involve any kind of specialist nurses? The gentleman has understandably been in a dark place for a while now, doesnt want company, wont eat or drink properly and just wants to sleep.all the time...really not like him at all. My dad bless him is physically and emotionally exhausted, I can see it's taking a huge toll on his own health, but I dont know where to turn to for help, it feels like a fight to get any help at all from GPs and district or community nurses and the lack of communication between them all just causes more stress. Sorry for the long post. Feel a bit lost and want to get some support for them both. 

Many thanks
