<unk>  involves the sensation of<unk>  in a part of the body that has been removed. The onset of<unk>  can occur within the first few days of amputation. The sensation may come and go, but can be continuous. While the sensation often affects the part of the limb farthest from the body, such as the foot of an amputated leg, other body parts closer to the brain, such as the arm or hand, can still experience similar sensations. Sensations can be described as shooting, stabbing, boring, squeezing, throbbing or burning. Sensations on smaller limbs and digits such as toes or fingers tend to be less severe. Sometimes the sensation feels as if the<unk>  part is forced into an uncomfortable position. Overall, the sensations may be triggered by pressure on the remaining part of the limb or emotional stress. Types There are various types of sensations that may be felt: *Sensations related to the<unk>  limb's posture, length and volume e.g. feeling that the<unk>  limb is behaving just like a normal limb like sitting with the knee bent or feeling that the<unk>  limb is as heavy as the other limb. Sometimes, an amputee will experience a sensation called telescoping, the feeling that the<unk>  limb is gradually shortening over time. *Sensations of movement (e.g. feeling that the<unk>  foot is moving). *Sensations of touch, temperature, pressure and itchiness. Many amputees report of feeling heat, tingling, itchiness, and<unk> . *In less severe cases where small digits are amputated, the sensation can be described as a tingling feeling as opposed to a<unk> ful sensation.
