How is phantom pain different from stump pain

How is phantom pain different from stump pain?

Phantom pain is generated by the CNS, whereas stump pain (also known as residual limb pain) originates from the peripheral nervous system, presumably related to an ill-fitting prosthetic, scar tissue formation, skin or tissue breakdown, ischemia, or development of a neuroma at the end of a severed nerve. Patients describe stump pain as aching, squeezing, throbbing, and stabbing pain localized to the distal stump. Stump pain may not present for several months after amputation. A patient may suffer from both phantom limb pain and stump pain. Patients with severe stump pain may be more likely to have symptomatic phantom limb pain.
