The expression "to hell and back" means to have gone through a very difficult and painful experience, often one that changes a person's life forever. It can be used to describe any kind of situation that is very challenging, such as recovering from an illness, dealing with a traumatic event, or overcoming a difficult obstacle. It's usually used to show that someone has come out the other side of a tough experience and is now stronger for having gone through it. For example, "She's been through hell and back since her accident, but she's still fighting and refuses to give up."
