Phantom limb pain (PLP) refers to ongoing painful sensations that seem to be coming from the part of the limb that is no longer there. The limb is gone, but the pain is real. The onset of this pain most often occurs soon after surgery. It can feel like a variety of things, such as burning, twisting, itching or pressure.
A herniated nucleus pulposus has the potential to irritate nerves, thereby causing pain, numbness or weakness in a limb. A person experiencing any of these symptoms should seek medical attention immediately.
