What is the difference between palliative care and comfort care?

Hi, I am taking care of my Ex of 23 years. He is diabetic, blind, heart attack, can't walk right side effected from a stroke. Placed him in a rehab for therapy. He ended up with 4 stage bed sores on the back and his heels, few other places, not all 4 stage it is all bad. The one on his back is very bad to the bone his kidney function is not good in terrible pain. The doctor said wound on the back is so severe it will not heal. He said he set up and appt for the palliative team could talk to me. Started talking about comfort his pain. Ask different things like feeding tube dialysis I said no, things that would prolong his life. My answer was no to all. Started comfort care, I'm confused. He is still alert, he knows whats going on. I ask him he doesn't want everything stopped. Just his pain under control, I wanted that stuff done when this function begins to shut down on their own. What do I tell them, comfort care or palliative care?
