your back will never be the same again, it takes a long time to just get over the pain, and it is the worst pain ever, ( i only trapped a nerve in my back and couldnt move for 2 weeks ) a slipped disk is 10 times worse than what i had.
you will always be getting a warning from now on when your back is about to go. So take it easy.
as Dutcho says keep mobile , i know its painfull but its better than seizing up, and you will mend a lot quicker.
You may suffer from sciatica from now on in your legs.
I might sound a bit like its torture, and believe me it is.
you will need to strengthen your back up soon, i recommend getting one of those Pilates Balls, it will help in controling your posture when sitting.
And most important when lifting things from now on, bend your legs and use your legs to lift
