How do doctors cut off a leg?

they would put u to sleep with nitrous oxide and cut it with scalpels and other medical tools. you will be feeling a bit of pain after the surgical occasion. They use more advanced tools for the bone cutting. you will be perfectly fine, but wont have an easy life with one leg, theres other advices u can abide, like having to buy a neurological, physical biological engineered robotic leg, its expensive is just to worry about though, your medical needs would be probably a wheel chair or crutches if the product is unaffordable.
