Nerve Damage In Ankle Symptoms

Chronic Knee Pain Treatment

Tinel’s Sign (Ankle)Peripheral Nerve Injury

Through years of experience, weve figured out that good and long-lasting chronic knee pain relief doesnt work unless all bases are covered.

The best knee pain management combines pain-reducing treatments with selected therapies like physical and psychological rehabilitation treatment.


What This Article Tells Us That Is New

  • In a review of more than 12,000 total knee arthroplasty patients during 20 yr, use of peripheral nerve blockade was not associated with peripheral nerve injury. However, patients with peripheral nerve injury were less likely to recover completely if they had received peripheral nerve blockade.

PERIOPERATIVE nerve injury is one of the most debilitating complications of surgery that commonly results in functional impairment, chronic pain, and decreased quality of life.Large retrospective epidemiologic studies have estimated the overall incidence of PNI at 0.030.05%.Although the majority of these injuries resolve over time,it is important for anesthesia providers to recognize risk factors that may predispose patients to PNI. Several procedural and patient-related characteristics have been implicated in PNI.Specifically, orthopedic surgical procedures may place patients at higher risk for PNI,with the incidence of neurologic dysfunction after total knee arthroplasty approaching 10%.

What Are The Symptoms Of A Knee Contusion

A knee contusion, also known as a bruised knee, is a bruise on or around your knee cap . This is fairly common among athletes and people who participate in physical activities that involve a lot of jumping, turning, and cutting.

Treating a bruised knee is typically just a matter of resting, icing, and taking over the counter pain medication. Your health care provider may also give you a brace or crutches.

Can The Nerve Damage Be Repaired

Lets talk about what exactly is the nerve made of, how is it composed, and then different types of injuries. So, if you look on the left-hand side here, the nerve is essentially layers upon layers upon layers of different protective connective tissue, ultimately protecting the nerve fibers, which, actually, transmit the electrical signal. Around that is myelin, which is insulation. Around that is the Perineurium, more insulation. Around that would be the Epineurium. Supporting that are the blood vessels on the outside of the nerve. So all of these help protect the nerve.

Now, if the nerve has been damaged, theres multiple different types of damage you can have.

You can damage:

  • inner fibers of the nerve .
  • complete severing of the nerve

Each one of these is a little bit more severe than the next, as well as sometimes theres more of a combination of nerve injury, not just one specific type of nerve injury.

What Is A Neuroma

A neuroma is a thickening of nerves in the ball of the foot which can feel like a small mass. Patients often describe it as the feeling of perpetually having a pebble in their shoe or a wrinkle in their sock. This nerve growth may also lead to tingling, burning, pain, or numbness at the site of the neuroma. The most common location for neuromas to appear is between the third and fourth toes, under the metatarsal bones . This is called a Mortons neuroma. But pain radiating into the second and third toes is the second most likely location of a neuroma.

Confirming If You Have A Neuropathy

Some people may need to see a neurologist in hospital for further tests such as:

  • a nerve conduction test where small metal wires called electrodes are placed on your skin which release tiny electric shocks that stimulate your nerves the speed and strength of the nerve signal is measured
  • electromyography where a small needle is inserted through your skin into your muscle and used to measure the electrical activity of your muscles

NCS and EMG are usually carried out at the same time.

Diagnosis Of Knee Pain

Checking Your Feet For Signs of Nerve Damage

A pain specialist or physician will start the process by asking detailed questions about the nature, severity, and duration of the pain. The patient may also be asked for details that determine the presence of one or more risk factors. A family history of conditions such as osteoarthritis is also useful. The appearance of other symptoms, as above, may also contribute to a diagnosis.

The region of the knee affected may also correspond to the underlying condition for example, pain in the kneecap may be indicative of patellofemoral pain syndrome. Visible abnormalities, if not associated with a fracture or dislocation, may increase the probability of a diagnosis of a sprain or strain. A report of the circumstances surrounding an accident can also aid a doctor when diagnosing knee pain.

Imaging techniques also contribute to the detection of conditions or injuries affecting the knee joint. These include:

  • Computerized tomography
  • Knee strengthening exercises

Foot & Ankle Nerve Injuries

Nerves are responsible for much of our brains ability to control our muscles. An injury to a foot and ankle nerve can cause the connected muscle to not function properly, or it can cause a person to lose feeling in the affected area.


Nerves are a fragile part of the human body that carry electrical impulses between the brain and rest of the body. Motor nerves carry the signals needed to make muscles move, whereas sensory nerves are what allows different areas of the body to respond to pain, pressure, and temperature.

A nerve is covered in a sheath of tissue, much in the same way electrical wires are sheathed in plastic for protection. Nerve fibers are called axons, which are separated into bundles within the nerve.

Foot & Ankle Nerve Injury Causes

Injuries that put pressure on or stretch the nerve can cause the conductive fibers within to break without disrupting the outer sheathing. Conversely, when a nerve is cut, both the axons and insulation are severed.

If the insulation remains intact, the nerve fibers farthest from the brain die. The end that is close to the brain remains alive, and over time may begin to heal.

If the nerve and insulation are both severed and the nerve is not repaired, the growing fibers can form a painful scar, called a neuroma.

What Can I Expect If I Have A Peroneal Nerve Injury

Recovery from a peroneal nerve injury varies depending on injury location and severity. For many people, symptoms improve or disappear completely with nonsurgical treatment.

Youre likely to make a full recovery if symptoms developed after a total knee arthroplasty. You are less likely to have symptoms go away entirely if you developed the injury after dislocating your knee.

What Are The Symptoms Of Tarsal Tunnel Syndrome

Tarsal tunnel syndrome causes signs of nerve pain. TTS usually causes pain in the inside of your ankle or the bottom of your feet. You may also experience:

  • Burning sensations.
  • Tingling or pins and needles sensations.
  • Weakness in your foot muscles.

Often, symptoms worsen during or after physical activity. If TTS is severe or long-lasting, you may experience symptoms all the time.

How Do You Treat Tarsal Tunnel Syndrome

Neuropathy of the Foot (Peripheral Neuropathy)

Many people can manage tarsal tunnel syndrome symptoms with at-home or over-the-counter treatments. You might try:

  • Rest: Staying off of your foot for a few days or weeks can promote healing and prevent further injury.
  • Ice: Use ice packs for up to 20 minutes, a few times a day. Icing your foot can reduce swelling and pain.
  • Compression and elevation: You may wear a supportive elastic bandage or brace around your ankle. Elevating your foot above your heart whenever possible can reduce inflammation.
  • Nonsteroidal anti-inflammatory medications : Over-the-counter NSAIDs such as ibuprofen may decrease pain and inflammation.

Your healthcare provider may also recommend nonsurgical treatments such as:

  • Braces, casts or splints: A cast or splint keeps your foot in place to encourage nerve healing. If you have flat feet or severe symptoms, your healthcare provider may recommend a brace to reduce pressure on your feet.
  • Orthotics: You may use custom-made shoe inserts . Orthotics can help your foot maintain a proper arch. This position reduces the movements that cause nerve compression. A stability or motion-controlled shoe also keeps your foot from rolling inward and reduces tension on your nerve.
  • Physical therapy: A physical therapist prescribes exercises and stretches to improve your strength and range of motion.
  • Steroid injections: Your healthcare provider may prescribe oral steroids or steroid injections to reduce pain and inflammation.

Treating Nerve Pain In The Foot And Ankle

by Dr. Robert J. Spencer | Jul 29, 2020

When you ask someone with nerve pain to describe what they feel, you might receive any number of possible answers:

  • Its tingling or numbing.

There can be quite a range of symptoms, but it should come as little surprise given that what is in distress here are the tools responsible for pain signals themselves!

In the more normal pain we feel the dull, achy, throbby, or sometimes sharp kind nerves next to damaged tissue transmit pain signals through the nervous system and to the brain to alert us that something is wrong.

However, when a nerve itself is damaged or irritated, it can cause problems along the path of that nerve and the way it transmits its signals. Not only can that interfere with the sensation of pain, but also sensitivity to it. In our feet, that can mean the simple act of putting on socks or having a bedsheet rub up against our toes can be shockingly painful!

Nerve-related pain in your feet or ankles is never something you should hold off on addressing in hopes of it going away. If a nerve is in distress, getting to the source of the problem and addressing it directly can save a lot of pain and potential future trouble.

We will dive further into what could be causing foot and ankle nerve pain here, but never hesitate to contact us should any of the above types of pain be bothering you. The sooner, the better!

What Is A Foot Or Ankle Nerve Disorder

This is any problem that causes a restriction or pressure on the nerves found in the feet or ankles. The most common nerve disorders that affect the feet and ankles include tarsal tunnel syndrome and Mortons neuroma, among others. Nerve conditions can be both painful and debilitating, and often require physical therapy or surgery to correct the problem.

We have extensive experience treating both diseases. Usually, treatment requires a combination of the following approaches:

  • Physical therapy
  • Orthopedic surgery

Foot And Ankle Neuropathy And Nerve Entrapment Causes

Identifying Nerve Pain in the Leg & Foot

Foot and ankle nerve conditions can occur because of injury, stress on the foot or ankle, diabetes and autoimmune diseases. Here are some of the most common types of nerve disorders.

  • Mortons neuromaThe tissue around the nerves that lead to the toes thickens, causing constant burning or pain in the ball of your foot.
  • Tarsal tunnel syndromeThe tarsal tunnel is the passageway that contains tendons and nerves that let the foot flex and move, including the tibial nerve. If the tibial nerve is compressed, you may experience numbness, burning or sharp shooting pains.
  • Baxters nerve entrapmentThe lateral plantar nerve runs across the bottom of your foot from the inner ankle side to the little toe. If the nerve becomes compressed in the heel, the result may be numbness and pain in the heel and sole.
  • Peroneal neuropathy The peroneal nerve is in the leg below the knee. Damage to the peroneal nerve can cause pain, tingling or numbness at the top of the foot. It may become difficult to raise your toes, your toes or ankle may feel weak, or your foot may feel like it is dropping when walking. In severe cases, you may be completely unable to lift your toes or foot or turn your ankle.

Symptoms Of Nerve Damage

Nerve damage symptoms are quite diverse and they usually appear rather slowly. Because the signs of nerve damage are gradual, there is a good chance they can at least be recognized and partially treated.

At times, they will signify a greater health issue, while sometimes the symptoms may be temporary and disappear. Regardless of what symptoms you experience, itâs recommended to get to a doctor for examination.

Diabetes & Foot Injuries

People with diabetes have higher chances of having nerve damage in their feet . Nerve damage can make it harder to feel sensations in your feet.

If you have diabetes, you may not feel cuts or sores on your feet. Even if your feet feel okay, its important to see a doctor after youve had a foot injury. Diabetes can also make it harder for cuts and sores in your feet to heal. Thats because diabetes weakens normal blood flow inside your body.

Knee pain is best initially assessed by a general practitioner . They will make an assessment and make sure there are no warning signs for something serious. If they suspect something more serious is causing knee pain, they may do some scans or blood tests and send you to see a pain specialist, neurosurgeon or spinal surgeon.

If the knee pain is mild or improving, GPs may:

  • Reassure that there is no serious cause for concern and advise that the knee pain should improve with physical activity and simple pain medications.

If the knee pain persists or returns GPs may:

  • Use stronger pain medications

  • Suggest management by an expert pain physiotherapist

  • Refer to a pain specialist physician to provide more comprehensive knee pain management using options like joint and nerve blocks, sympathetic blocks and radiofrequency ablation , pulsed radiofrequency or nerve stimulation and neuromodulation using spinal cord stimulation.

  • Refer to an orthopaedic surgeon for an opinion.

Other Causes Of Foot Pain

There are also several other conditions that can cause pain similar to a pinched nerve in the foot. These conditions include:

  • Peripheral neuropathy.This condition happens when nerves on the periphery of your body, most often in the hands and feet, are damaged. This can lead to a variety of symptoms, including pain, tingling sensations, and muscle weakness. Many things can cause peripheral neuropathy, including but not limited to diabetes, autoimmune diseases, high blood pressure, some vitamin deficiencies, and some medications.
  • Plantar fasciitis.This can occur when the long ligament on the bottom of your foot, the plantar fascia, becomes inflamed. It can lead to pain at the heel or bottom of the foot.
  • Sciatica.This condition occurs when your sciatic nerve becomes pinched or irritated. It can lead to pain that may radiate down the leg or to the foot.
  • Stress fractures. These are small cracks that occur in bones as a result of repetitive activities or overuse. When a stress fracture happens in the foot, you may feel pain during physical activity that goes away with rest.

If you think you may have a pinched nerve in your foot, there are self-care measures you can take to help ease the symptoms. Here are some home remedies you may want to try:

Causes And Symptoms Of Sural Neuritis

Irritation or damage to the sural nerve is known as sural neuritis, and its more common than you think. Damage to your sural nerve can come from a number of different sources, but the most common way a person injuries their sural nerve is during an ankle sprain. The nerve can also be irritated due to inflammation or swelling, or as a result of a surgery gone wrong, although it is rare that a surgeon will damage the nerve. More often, surgical repairs in the area result in scar tissue formation that irritates the nerve.

Symptoms of sural nerve irritation include:

  • Pain on the outside of the foot
  • A burning sensation
  • Symptoms that are aggravated by direct pressure
  • Hypersensitivity
  • Localized tenderness
