The simplest answer is no, braces don't hurt. They don't hurt when they are put on and you don't have to be numb. What happens is that your teeth may feel a little sore, especially a day or two after you see the Dentist that is taking care of your orthodontics treatment. Some people feel a lot of tenderness but some people don't feel much at all. Some people have to adapt by only eating soft foods for a few days. But, the key is: it's only temporary, and it's only soreness, never a constant pain.
