Unraveling the Enigma Phantom Limb Pain in ਀ Underresearched Populations Written by Tingting Chung | Edited by Michael Go | Designed by Laura Jannetta Within the intricate web of human physiology is a Amputation may lead to neuroma formation, perplexing and captivating enigma known as generated hyperexcitability, and spontaneous phantom limb pain (PLP): the perception of pain and discharges. Evidence depicts that this may further discomfort in a limb that no longer exists. Coined in exacerbate stump pain, including PLP. At the spinal the sixteenth century by French military surgeon cord and brain levels, increased sensitivity and Ambroise Paré, PLP remains a poorly understood and altered brain maps due to neuroplasticity may occur, difficult-to-treat condition, and there is limited which are linked to the intensity of PLP [4]. literature on its underlying pathophysiology [1]. In Psychological factors may also play a role in PLP: the United States, 30,000 to 40,000 amputations are stress and anxiety can worsen pain, particularly in performed each year, with pain after amputation as individuals who have difficulty managing such the most common symptom [2].
