See below: Phantom limb pain is a phenomenon that can occur after a person has an amputation of a limb or part of a limb. For many years, the dominant hypothesis for the cause of phantom limbs was irritation in the peripheral nervous system at the amputation site (neuroma). The therapy has had some success in alleviating pain associated with “learned paralysis,” often experienced by patients whose missing limbs were paralyzed prior to amputation. By the late 1980s, Ronald Melzackhad recognized that the peripheral neuroma account could not be correct, because many people born without limbs also experienced phantom limbs. When the patient views the reflection of the intact limb in the mirror, the brain is tricked into “seeing” the phantom limb. Approximately 80 to 100% of individuals with an amputation experience phantom sensations in their amputated limb. Treatment approaches have included medication such as antidepressants, spinal cord stimulation, vibration therapy, acupuncture, hypnosis, and biofeedback. Phantom pain is pain that feels like it's coming from a body part that's no longer there. Both the brain and the peripheral nervous system may be involved. "[22], Phantom sensations may also occur after the removal of body parts other than the limbs, e.g. There may be feelings in the limb as if it were still attached to their body. The mirror box provides a reflection of the intact hand or limb that allows the patient to "move" the phantom limb, and to unclench it from potentially painful positions. [17] Perineural catheters that provide local anesthetic agents have poor evidence of success when placed after surgery in an effort to prevent phantom limb pain. Phantom limb pain is very real, and it is quite common in amputation patients - so you have reason to be concerned. Nonpainful sensations can be divided into the perception of movement and the perception of external sensations (exteroception), including touch, temperature, pressure, vibration, and itch. The changes in the brain that contribute to the success of this therapy are not completely understood, and information from long-term studies on the use of mirror box therapy is scant, although several patients have reported long-term relief. He was the first person to consider sensory perception as the underlying phenomenon of the syndrome. Phantom pain is pain sensation to a limb, organ or other tissue after amputation and/or nerve injury.5 In podiatry, the predominant cause of phantom limb pain is after limb amputation due to diseased state presenting with an unsalvageable limb. [21] A 2018 review, which also criticized the scientific quality of many reports on mirror therapy (MT), found 15 good-quality studies conducted between 2012 and 2017 (out of a pool of 115 publications), and concluded that "MT seems to be effective in relieving PLP, reducing the intensity and duration of daily pain episodes. Phantom Limb Syndrome. A phantom limb is the sensation that an amputated or missing limb (even an organ, like the appendix) is still attached to the body and is moving appropriately with other body parts. Occasionally, the pain can be made worse by stress, anxiety and weather changes. Although the painful symptoms of phantom limb syndrome resolve on their own in some patients, other patients may experience severe, sometimes debilitating chronic pain. This is called phantom limb awareness, that is often accompanied by specific sensory kinaesthetic sensations (phantom sensations); patients sometimes feel as if they are gesturing, feel itches, twitch, or even try to pick things up. [3], People will sometimes feel as if they are gesturing, feel itches, twitch, or even try to pick things up.

Certain drugs, such as ketamine (an anesthetic) and calcitonin (a hormone), administered prior to amputation surgery lessen the likelihood of development of later pain symptoms.
