I have a friend who had to amputate his leg because of a car accident. Whenever he takes a bath or walks, he always feels physical pain. Especially when taking a bath, water will flow to the amputation site. He will feel uncomfortable and sometimes make him sweat. People say that this symptom is not a psychological problem, but a phantom limb disease.
Phantom limb disease is that patients still don't admit that they have physical defects and feel that they are still complete. They can't accept that the limbs that have been with them for more than ten years or even longer are gone. This is a normal behavior, called phantom limb disease. That's because people's body feels rich and their cerebral cortex is active. People will feel pain, not their psychological problems. This really happened.
When people feel physical pain after amputation, scientists have studied the pain. According to research, this kind of pain is related to the control area of the brain. When the amputee has phantom limbs, there will be signal activity in the human brain area, and the patient will think that the amputee's defect is the same as that of a healthy limb. When amputees have this problem, don't always endure this pain. If this problem occurs, you should go to the hospital for treatment immediately, and you can take medical equipment to relieve the pain in your limbs. And sometimes I feel pain in my limbs and my limbs will become inflamed. When you touch water or sunlight, you will feel abnormal pain.
