Post-amputation pain is a form of chronic pain that can develop after the surgical removal of a limb.
The two main manifestations are:
- Phantom limb pain: a painful sensation perceived in the part of the limb that is no longer there
- Stump pain: pain localized in the residual part of the amputated limb
How Common is it?
According to scientific literature, between 30% and 80% of patients who undergo amputation develop a form of chronic post-operative pain.
This can include phantom limb pain, stump pain, or both.
Why Does it Happen?
Post-amputation pain can be caused by multiple factors:
- Changes in the central nervous system: the brain continues to “perceive” the limb even though it’s no longer there
- Neuroma: an abnormal growth of nerve endings in the stump
- Local inflammation or deep scarring
- Psychological factors: anxiety, insomnia, or depression can influence pain perception
Phantom limb pain, in particular, can manifest as:
- Burning, stabbing, cramping, electric shocks
- Sensation of incorrect positioning of the missing limb
- Worsening with stress, cold, prosthetic use, or inactivity
How is it Diagnosed?
- Specialized pain assessment, based on the patient’s account and clinical examination
- In some cases, ultrasounds, magnetic resonance imaging, or EMG are used to rule out neuromas or inflammation
- There is no “single” examination: clinical experience and a personalized approach are fundamental
What treatments are available?
Drug treatment
- Medications for neuropathic pain (e.g., gabapentin, pregabalin, amitriptyline, duloxetine)
- Low-dose ketamine infusions (in selected cases)
Physical Therapies and Neuromodulation
- TENS (transcutaneous electrical nerve stimulation) on the stump or related areas
- Mirror therapy or virtual reality
- Functional rehabilitation and use of sensitive prostheses
- Occupational therapy and psychological support
Interventional Therapies
- Ultrasound-guided nerve blocks (on the sciatic, femoral nerve)
- Local stump infiltrations, in case of neuroma or inflammation
- Pulsed radiofrequency for painful neuromas
- Spinal neuromodulation (in refractory chronic cases)
What is the Prognosis?
Many patients find a significant improvement in pain and quality of life thanks to a personalized and multidisciplinary approach. Even if the pain may persist over time, we now have effective strategies to reduce and manage it.
