Most people who have experience an amputation of a limb experience a sensation where the missing body part is still there. This is known as a phantom limb and can be a very painful experience. They could also experience abnormal temperature perception such as being hotter or colder than the "rest of their body". It is not generally something that lasts forever and symptoms will usually decrease over time. One form of treatment is the use of mirror box therapy in which a patient will use a mirror or insert the opposite limb into a box of mirrors which "tricks" his/her brain into thinking the missing limb is still there. Below is a picture of what mirror box therapy looks like.
