Residual Limb Pain
Overview
Pain in the remaining part of a limb after amputation, sometimes called stump pain, is common. About half of people who have an amputation experience this type of pain. It can start soon after the surgery, often within the first week, but it might also persist even after the area has healed.
While this pain isn't usually intense, it can feel like different things: throbbing, burning, squeezing, or stabbing. In some cases, the remaining limb part might move unexpectedly, a little or a lot.
It's important to understand that this type of pain is distinct from phantom pain, which feels like the pain is coming from the missing limb. However, they often go together. Studies show that more than half of people who experience phantom pain also have pain in the remaining limb part.
Several things can cause this pain:
- Issues with the bone or soft tissues: Problems with how the bone or surrounding tissues heal or are affected by the surgery.
- Infection: A bacterial infection in the remaining limb.
- Poor blood flow: If the blood supply to the area is not adequate, this can lead to pain.
- Tumors: In rare cases, a tumor in the area can cause pain.
- Prosthetic issues: The fit or use of an artificial limb (prosthesis) can sometimes contribute to the pain. For example, if the prosthesis isn't properly fitted, or if the person isn't using it correctly, they might experience discomfort in the residual limb.
Diagnosis
Understanding Residual Limb Pain: Diagnosis and Treatment
It's crucial to pinpoint the cause of residual limb pain to get the right treatment. Sometimes, the cause can be fixed. Doctors use several methods to find out what's causing the pain.
Physical Exam:
Your doctor will carefully examine your residual limb. This includes looking for any skin problems like sores or breaks, checking for bone issues, and looking for signs of infection or lumps. They will also tap on the limb to check for a neuroma, which is a collection of nerve endings that can form after amputation and cause pain.
Imaging Tests:
Different imaging tools can help determine the source of the pain. These include:
- MRI (Magnetic Resonance Imaging): This uses powerful magnets and radio waves to create detailed pictures of the soft tissues and bones in your residual limb. It can show things like swelling, tumors, or nerve damage.
- CT (Computed Tomography) Scan: This uses X-rays to create detailed cross-sectional images of your limb. It can help detect fractures, bone bruises, tumors, or infections.
- X-rays: These are a common imaging technique that produce images of bones. They can show fractures and other bone problems.
- Ultrasound: This uses sound waves to create images of the soft tissues and organs. It can be useful for looking at soft tissue injuries or swelling.
These tests can help rule out other possible causes of your pain, or confirm a suspected problem.
Blood Tests:
Sometimes, blood tests are needed to rule out infections or other underlying medical conditions that might be causing the pain. These tests can help your doctor narrow down the possibilities.

Treatment
Dealing with pain after amputation? Treating residual limb pain often means finding the reason behind the discomfort. In about half of cases, the pain improves on its own without any special treatment. However, when treatment is needed, here are some options:
Medications:
-
Over-the-counter pain relievers: Simple pain relievers like acetaminophen (like Tylenol) and nonsteroidal anti-inflammatory drugs (NSAIDs) can help. Stronger medications, such as opioids, might be necessary, especially if the pain is related to problems with the skin, muscles, soft tissues, or bones.
-
Anticonvulsants: Drugs like gabapentin (Gralise, Neurontin) and pregabalin (Lyrica) can help if the pain is from damaged nerve fibers. These medications work by altering how nerve signals are sent to the brain, effectively reducing the pain sensation.
-
NMDA agonists: These medications, including ketamine, target the source of increased sensitivity in nerve cells. They're usually applied directly to the skin (topical) and can be quite effective at reducing pain. However, the pain relief is often temporary, and these medications can have side effects.
Other Treatments:
-
Massage: Gentle massage of the residual limb can sometimes lessen the pain.
-
Hypnosis: A small study showed that several hypnosis sessions helped reduce residual limb pain in some people.
-
Nerve blocks: Injecting a medication to temporarily block or reduce nerve signals can help with pain. This can also help pinpoint the cause of the pain, like a neuroma (a growth on a nerve), if the pain stops after the injection.
-
Neuromodulation: These treatments use electrical stimulation to ease pain. Different types of neuromodulation are available, including spinal cord stimulation (SCS), peripheral nerve stimulation (PNS), and transcutaneous electrical nerve stimulation (TENS). These methods can help relieve residual limb pain.
It's crucial to remember that these treatment options may not work for everyone, and the best approach will depend on the specific cause and severity of the pain. Always discuss these options with your doctor before starting any new treatment.
