Hi Jennie and Erik, hope you are both fairing well. Just wanted to share that my John had to experiment with his syringe feedings to get them slowed down enough that his stomach would tolerate the amount he needed each feeding.And we cut the suppliment with water during each feeding. As to the swelling, I think that's pretty normal and can go on for quite a while. John still has pockets on his face that are swollen every morning and stay that way during the day. Don't know alot about the hot tub, except that I would be concerned about raising his body temp. while he is in a weakened condition. Hot tubs can be dangerous for healthy people. Take care of yourselves. Amy
