Dad finally came home on Saturday after 3 weeks and 2 days in the hospital, but he has 4 different oxygen machines, tanks, nebulizer, etc to use until his lungs heal. He's been enjoying long walks with his tanks. Kind of like scuba diving on land ;-) It seems the Oxaliplaten chemotherapy drug and the Keytruda immunotherpay medications accidentally gave him a form of cystic fibrosis as a side effect :-( so doctors are giving him steroids and a preventative antibiotic medication and hoping he'll go back to normal. Since it wasn't a naturally occurring thing they're hoping it'll reverse itself.
Thankfully he's eating somewhat OK. He occasionally chokes and vomits maybe every other meal or so, but is mostly able to eat. His appetite and taste are coming back after a month of no chemo. His hair and eyelashes are also starting to come back. His fingers and hands stopped hurting, now they're just numb, but his toes and feet still hurt from the cold.
Lots of doctor appointments this week to follow up. He's off chemo until further notice.
