I went home on day 5. I had prepared for food that I could open and manage with one hand because I (erroneously) assumed I would have pain in the arm on that side - but no such issue.

I had prepared some meals and froze them and bought frozen entrees I enjoy and squeeze peanut butter and ice cream
And having meals like egg cups and chicken pie etc already made was helpful. Also I would have band aids and maybe a few sterile bandages and tape for your incision.
Oh. You may ooze out of the incision. Put old sheets on your bed before you go, and a towel under the sheet where you will lie - because that fluid will stain linens and your mattress cover. Ditto old pajamas.

If your shower has a handheld attachment that makes it easier to avoid the wound when shampooing, etc. get a baseball cap or bandana because your hair will be a fright for a while. 🙂

On balance, I didn’t really have an issue caring for myself.

Best of luck!!
