Saul, your sister needs to talk to the doctor tomorrow about the problems your father is having. Even though you do not see the doc face to face it doesnt mean you couldnt give them a call too. Make sure your father has signed all the necessary HIPPA papers so that his medical team will speak to you and yoru sister. Regardless of what caused your fathers cancer, he has it and is being treated. Being
HPV+ gives a better chance of no recurrances.
If his sleeeping is that bad and he isnt getting nutrition then something needs to be changed asap. As I mentioned above there are the fentanyl patches for pain which will last 3 days. A sleeping pill can also be prescribed. His breathing problems muct be addressed with the doc.
If your father is not taking in enough nutrition then he will feel terrible. If he had proper nutrition and hydration then he would feel so much better. I went into more detail in my previous post.
Best of luck with getting your father the help he needs. Make sure either you or your sister speak up since obviously he is not making his needs heard. I am speaking from experience, I was malnurished and dehydrated due to not taking in enough. Several times I ended up in the hospital from this. Ask the hospital if they have a visiting nurse that can come out to help him too. I had a nurse come out every few days to check on me. Dont be timid about speaking up, your dad needs your voice right now while he is in this weakened state.
Please check back with us and I hope I was able to give some assistance.
