My dad was so cold when he was getting his tx too. He was cold until about one month post treatment. We also had the problem with the PEG tube and were clueless, they took xrays to make sure there wasn't a blockage. Once he was put on the drip (super slow) he was fine. This was only during his tx. Once tx is completed he will be so much better. Everyone here is so helpful. Ask questions, it seems like the drs don't really explain things too well. Good luck and God Bless
