My 86 year old dad with terminal prostate and blood cancer, took a bad fall and was in ICU for a week then 5 days in a regular hospital then 3 weeks in a rehab center. He had to also to regain normal function of pretty much everything. That rehab center, of which I had heard awful stories about them, was a godsend with pt, ot and speech therapy. He’s home now, cancer is probably kicking in badly, but I will always be thankful for that place to get him home.Yeah, she getting that & I understand from them it'll take time to regain normal body functions again that many of us take for granted each day.
Please give your wife time. One step forward, 2 steps back. 1 step forward, etc. it will come.
