Kathy .....
Adding my welcome to the group!
As for needing someone to care for you when you get home: it all depends on how you do post-operatively. Many of us had virtually no lingering issues, but complications can arise. My vote would be to arrange for someone to be with you (or you with them) the first week you are home from the hospital ..... and then have a Plan B, if you need further assistance beyond that. It would also be good to have someone cooking your meals for you for a couple of weeks so you can concentrate on healing by resting, walking, resting, etc.
I am married, but my husband had to return to work 10 days after my surgery so our daughter-in-law came with her 3-year-old and stayed with me for the next week. I really would have been fine by myself, but it reassured the family to have them there.
Each person is very different, but I would have some options lined up just in case you need them.
Best thoughts. Clarice
