Detailed explanation-1: -When a body part is amputated, the nerve connections from the periphery to the brain remain in place. The brain can misinterpret the information it’s receiving or process the signals as the sensation of pain, even if the amputated portion has since been removed.
Detailed explanation-2: -Another example of this rewiring: When you touch one body part–say, your hip or your forearm–your brain might sense it on your missing limb. Other possible causes of phantom limb pain include damaged nerve endings and scar tissue from the amputation surgery.
Detailed explanation-3: -Stump and “phantom limb” pain Phantom limb sensations are sensations that seem to be coming from the amputated limb. Occasionally, these can be painful (phantom limb pain). The term “phantom” does not mean the sensations are imaginary.
Detailed explanation-4: -After one of your limbs is amputated, you may feel as if the limb is still there. This is called phantom sensation.
Detailed explanation-5: -Finally, phantom limbs also allow us to explore intersensory effects and the manner in which the brain constructs and updates a “body image” throughout life. The phenomenon of phantom limbs has been known since antiquity and has always been shrouded in mystery.
