Doctor's Bag (Fallout: New Vegas)

A doctor's bag is an aid item in Fallout: New Vegas.

Characteristics
Doctor's bags and getting healed by a doctor are the only ways to heal crippled limbs during Hardcore mode. Note that if you choose to go to normal mode, you can heal crippled limbs with stimpaks but you can not go back to Hardcore mode after that. It will also require high science and medicine skills to heal crippled limbs with a doctor's bag.

Three can be obtained by pre-ordering the Mercenary Pack, although it can still be found in the game without it.
