Temperature feedback is a nice sensation because you feel the limb, the phantom limb, entirely. It does not feel phantom anymore because your limb is back.

The pain is real, but it feels like it’s happening in the missing body part. It has been reported to occur in 80-100% of amputees, and typically has a chronic course, often resistant to treatment. Research continues to explore the underlying mechanisms of phantom limb pain (PLP) and [...]
