Do people walk again properly just like before after getting a gunshot/firearm wound to the leg?shot to eye leads to blindness,...is leg survivable?

Yes: Depending on where the person was shot, most people can walk again after such a trauma.

Sometimes: Depends on the degree of damage inflicted as well as what structures are affected If only muscle affected usually recover fine if medical attention prompt but injuries to bine and joint areas can b much bigger problem. Also injuries to blood vessels in thigh or groin can be fatal
