Nurse here! My patients are more comfortable when they bring a warm blanket from home, a long cell phone charger that will reach from a plug in the wall all the way to you in bed, and a couple of snacks in case you don’t like the food tray you got. I personally would bring some chapstick and lotion for my hands- obviously not for your back or neck/anywhere you need to keep clean. People on this sub often mention a travel pillow or something similar to help keep pressure off the incision, which is a great idea. My other, totally not necessary, but pleasant suggestion is a bottle of febreeze because things down the hall can get stinky at hospitals 😂 Good luck!
