What is phantom limb pain? How to ease this particular pain

You may also have this question"My legs are gone, so why do I still feel pain in my toes?"This is one of the most common and confusing experiences of amputees after surgery. The amputated limb obviously no longer exists, but the pain actually exists in the brain - this phenomenon is called phantom limb pain.

1. What is phantom limb pain? Phantom limb pain refers to the pain that amputees feel in the part of the limb that has been amputated. This kind of pain is not a "psychological effect" or "imagination", but a pain with a real neurophysiological basis. The patient's subjective feeling is exactly the same as the real pain. Statistics show that about 60-80% of amputees will experience varying degrees of phantom limb sensation after surgery (phantom limb sensation is not necessarily accompanied by pain), and about half of them will develop painful phantom limb pain. 2. Why does phantom limb pain occur? The current mainstream explanation is the cerebral cortex reorganization theory: the sensory cortex area of the human brain is like a map, and each part of the body corresponds to a specific area. After amputation, the brain area originally responsible for sensing the limb loses input signals and will be "occupied" by surrounding areas, forming abnormal neural circuits. When these abnormal circuits are activated, the brain mistakenly thinks that the limb that no longer exists is sending pain signals. In addition, the amputated nerve endings form neuromas on the stumps, which may also continue to send disordered signals to the brain. 3. What are the symptoms of phantom limb pain? · Burning, stinging, cutting sensation· The feeling that the limb is "stuck" or spasmodic· The pain often appears suddenly like lightning and lasts from seconds to hours· It is easy to aggravate when the weather changes, emotional tension, and stress4. Effective relief methodsMirror Therapy (Mirror Therapy)This is one of the non-drug therapies with the most sufficient clinical evidence. The method is to place a mirror between the legs, allowing the patient to see the mirror image of the healthy limb to "replace" the phantom limb, tricking the brain through vision and helping to reconstruct the correct neural mapping. Research shows that consistent mirror therapy can significantly reduce the intensity of phantom limb pain. Progressive desensitization trainingThe rehabilitation therapist provides light to heavy tactile stimulation (slapping, massage, touching with different materials) on the stump to help the brain re-establish correct sensory feedback. Drug treatment (as directed by your doctor)Gabapentin and Pregabalin - commonly used drugs for neuropathic pain; tricyclic antidepressants - have certain effects on chronic phantom limb pain. Specific medication must be carried out under the guidance of a doctor. Transcutaneous Electrical Nerve Stimulation (TENS) (Follow doctor’s advice) Send low-frequency electrical pulses to nerves through skin surface electrodes to interfere with pain signal transmission. Some patients report significant relief. PsychotherapyCognitive behavioral therapy (CBT) helps patients change their perception and coping style of pain and reduce the impact of pain on daily life. 5. Editor's suggestion"Phantom limb pain is real pain, not hypocritical, and amputees do not have to bear it alone. Early intervention is more effective than delayed treatment."Practical tips:· Keep a diary of phantom limb pain (time, intensity, triggers) to help doctors develop personalized plans· Early wearing of prostheses itself can also help reduce phantom limb pain - normal proprioceptive input can inhibit abnormal neural activity· Do not increase the dose of painkillers by yourself, long-term dependence on opioids has the risk of addiction· Don’t avoid talking about phantom limb pain. Communicating with your doctor and family is the first step in treatment6. What situations require timely medical treatment? · Severe pain that affects sleep for more than 2 weeks· Conventional analgesics are ineffective· Accompanied by depression and anxiety· Redness, swelling, and fever in the stump (infection or neuroma formation need to be ruled out)Summary1. Phantom limb pain is a neurophysiological phenomenon, not a psychological problem, and deserves serious treatment and treatment2. Mirror therapy is the preferred non-drug solution, which is simple and easy to implement and has sufficient clinical evidence3. Early wearing of prostheses itself has a positive effect on reducing phantom limb painThe treatment of phantom limb pain requires an individualized plan.
