[54F] With tingling and numbness in left ankle

Patient Description

A 54-year-old female has been experiencing a tingling and numb sensation in her left ankle for the past couple of weeks. The sensation is similar to when a foot or hand falls asleep and is primarily localized to the top part of the ankle, sometimes extending slightly to the top of the foot. These symptoms worsen when sitting for long periods, especially with legs crossed, but improve after a full night's rest or when lying down for 5-8 hours. There is no swelling or pain associated with the symptoms. The patient has no history of recent injuries to the back or neck, no changes in walking ability, and no weakness in the ankle or foot. Occasional bladder issues have been ongoing for a couple of years. The patient is not currently taking any medications and has no known pre-existing conditions or chronic illnesses.

Arora's Assessment

What might be happening

Based on the information you've provided, here are some possible explanations for your symptoms:

  • Nerve Compression or Entrapment: The tingling and numbness in your ankle could be due to nerve compression, possibly from sitting in certain positions for extended periods. This is similar to how your foot or hand might "fall asleep" when pressure is applied to a nerve.

    • Treatment: Often, this can be managed by avoiding positions that cause the compression. If the symptoms persist, a doctor may recommend physical therapy or other interventions.
  • Peripheral Neuropathy: This condition involves damage to the peripheral nerves and can cause tingling, numbness, and other sensations. While it often affects the hands and feet, it can also affect other areas.

    • Treatment: Managing underlying conditions (like diabetes), medications, and lifestyle changes can help alleviate symptoms.
  • Tarsal Tunnel Syndrome: This is a condition where the tibial nerve is compressed as it travels through the tarsal tunnel near the ankle, leading to tingling, numbness, and sometimes pain.

    • Treatment: Rest, ice, anti-inflammatory medications, and sometimes physical therapy or surgery may be recommended.

What you can do

While you should consult a healthcare professional for a formal diagnosis, here are some steps you can take to potentially alleviate your symptoms:

  1. Avoid Prolonged Sitting with Legs Crossed: Try to sit with both feet flat on the ground and take breaks to stand and move around.
  2. Adjust Your Sitting Position: Use a footrest or adjust your chair to ensure your legs are not under pressure.
  3. Stretch and Exercise: Gentle stretching and exercises that improve circulation can be beneficial.
  4. Maintain Good Posture: Ensure that your sitting and standing posture is correct to avoid unnecessary pressure on your nerves.
  5. Rest and Elevate: When resting, elevate your legs to improve circulation.

What you should look out for

Seek medical attention if you experience any of the following:

  • Worsening Symptoms: If the tingling and numbness become more frequent or severe.
  • New Symptoms: If you develop pain, weakness, or changes in your ability to walk.
  • Changes in Bladder or Bowel Control: Although you mentioned occasional bladder issues, any significant changes should be evaluated by a doctor.
  • Persistent Symptoms: If the symptoms do not improve with rest and position changes.

Remember, while these suggestions can be helpful, they are not a substitute for professional medical advice. Please consult a healthcare provider for a thorough evaluation and appropriate treatment.

People Also Ask


What causes tingling and numbness in the ankle without pain or swelling?

Tingling and numbness in the ankle without pain or swelling can be caused by nerve compression or entrapment, peripheral neuropathy, or conditions like tarsal tunnel syndrome. These issues can result from pressure on nerves, often due to certain positions or underlying health conditions.


How can sitting positions affect nerve compression in the ankle?

Sitting positions, especially with legs crossed, can put pressure on nerves in the ankle, leading to compression. This can cause sensations similar to when a limb 'falls asleep.' Adjusting sitting positions to avoid pressure on the nerves can help alleviate symptoms.


What is tarsal tunnel syndrome and how is it treated?

Tarsal tunnel syndrome occurs when the tibial nerve is compressed as it passes through the tarsal tunnel near the ankle. It can cause tingling, numbness, and sometimes pain. Treatment options include rest, ice, anti-inflammatory medications, physical therapy, and in some cases, surgery.


When should I seek medical attention for tingling and numbness in the ankle?

You should seek medical attention if the tingling and numbness worsen, if you develop new symptoms like pain or weakness, if there are changes in your ability to walk, or if there are significant changes in bladder or bowel control. Persistent symptoms that do not improve with rest and position changes should also be evaluated by a healthcare professional.
