Victims of torture, if they live, may be in physical pain for years following the torment. The specific pains depend on the type of torture they had to endure. Muscles may have been torn, crushed, damaged through exposure to electricity, stretched beyond their capacity, or even destroyed. Bones may have been broken and left to mend on their own or repeatedly damaged. Tendons may be damaged. Nerves may be destroyed through exposure to electricity, heat, repeated blows, or chemicals. Ears may ring or hurt due to blows to both ears at the same time. Headaches may be the result of repeated blows to the head.
