Why do scars have no feelings?

I broke both bones in my arm. Compound fracture. Its been about 9 months. The scar doesn%26#039;t feel anything. You can use nail clippers and squueze at the scar ( i know its reallyy disguting) But I dont feel anything.|||Scar tissue has no blood supply built into it like the capillaries under your normal skin tissue. It is just a fibrous covering.|||It is damaged tissue with no nerve endings because of the injury.|||around the scar, the nerves are damaged that cause the feeling sensation.
