Seamom did a ‘shopping list’ for surgery: Surgery shopping list
If you have a smoothie maker/ juicer in the kitchen then they’re great post-surgery. I had lots of yoghurt too. A wedge pillow to keep you propped up is good, and I found a V-shaped orthopaedic pillow (like you have for breastfeeding) was really comfy as it eases the pressure from the sides of your neck.
B group vitamins are supposed to help with nerve healing.
Obviously you won’t be able to take everything with you, but just a heads up so that you can get stuff in for home too. Also some sort of massage oil for the scar for later is good too.
Good luck, and hopefully the wait won’t seem too long…
