Is phantom limb pain either biological or psychological?

Neuropathic: This phenomenon is consider a neuropathic pain. There is a disconnect between what the brain perceives and what is actually there. Phantom limb syndrome is common to many if not all amputees but not all have phantom limb pain. Early use of a prosthesis is essential to help reduce these symptoms. There are excellent medications that can also help with the symptoms. See a pm&r physician.

Neurological: It's physical/biological but stress can make it worse.
