5 Reasons for Foot Numbness

The sensation of foot numbness closely resembles what is often referred to as “pins and needles”. It feels like you have been sitting on your foot for extended periods of time causing restricted blood flow and resulting in numbness.If it happens when you are running, there is obviously a deeper cause for the numbness.

Many experience either a numbness in a particular area of the foot or in other cases, your entire foot may turn numb. The following are five of the main possible reasons why your foot is numb when you run.

1. Compression of the Sciatic Nerve

Sciatica

What Is Sciatic Nerve

The sciatic nerve is the nerve that starts from the lower part of your spine and ends in your foot. It plays an important role in connecting the leg to the foot muscles through the spinal cord. If you experience a numbing sensation in the base of the foot, it may be a result of compression of the sciatic nerve.

Some Noticeable Symptoms

The nerve may be compressed by the muscles that overlie the nerve. When this happens, you may experience numbness. There are additional symptoms to help you identify whether this is the cause of your numbness including:

  • There is a sensation that you can feel originates in the lower back or buttocks area and continues to the foot
  • Aside from numbness, you feel a dull ache in your foot
  • There is a tingling sensation that you can feel down your leg

2. Foot Trauma Caused By Injury

Take It Easy

One of the common causes for foot numbness is getting back to your running routine too fast after having a foot injury. After enjoying a fixed running routine and then having to lay low for a while because of injury, it is easy to underestimate your recovery.

  • Getting back to your running routine too fast can cause the tissue in the foot to swell and lead to numbness.

What You Should Do

If you have had an injury and get foot numbness, consider taking the following steps:

  • Return to low-intensity workouts if you feel any discomfort when running
  • Understand the cause of your injury and address it
  • Do strength and flexibility exercises while you wait for your complete recovery
  • It is also good to remember that some injuries may be totally unrelated to the foot but still cause numbness. For example, a slipped disc in your back can cause the numb feeling.

3. Wearing Shoes That Don’t Fit Well

What Is Your Problem

Wearing shoes that are too tight may hinder proper circulation of blood in the body causing foot numbness. Constantly putting your feet in tight shoes may, in the long run, cause the nerves to compress.

  • This may be the cause of your numbness if you also experience other signs that you have ill-fitting shoes.

Signs To Look Out For

  • You get blisters on your feet
  • You experience inflamed tendons especially on the inside of the ankle or the outer part of the foot. This is caused when the arch of the shoe doesn’t provide enough support.
  • You have cracked or cut toenails or bruised toes when you wear your shoes

Your Solution

If you discern that this is the cause of your foot numbness, the easiest solution is to get proper fitting shoes.

  • You may need to consult a professional to make sure.

4. Having a Certain Foot Structure

Certain Foot Structure

Your Natural Feet

Some people who have flat feet experience foot numbness because of their condition. This is because the nerves may easily be compressed when the feet are flat. 

  • According to statistics, about 20% of the population in the UK suffer from some sort of flat feet.

Some Noticeable Symptoms

Although many have learned to compensate for their flat feet, some symptoms caused by flat feet may include:

  • Lack of balance
  • Feeling of foot stiffness
  • Painful feet in different areas. This pain depends on the area of the foot that has injured tendons. It usually is in the arch, on the outer edge of the foot or inside of the ankle

Your Solution

If you experience any of the mentioned symptoms and have not officially checked whether you have flat feet, this may be the time to consult a physician.

5. Diseases such as Diabetes

Diabetes And Your Health

This is a more serious cause for numbness in your feet that has nothing to do with any nerve damage or foot condition. Some diseases such as diabetes can affect the function of the nerve system. Because of the increase in blood sugar, blood flow to the nerves is affected causing damage. The condition is referred to as diabetic neuropathies.

If you have been suffering from diabetes for some time, you may experience numbness or a tingling feeling in your hands, feet and other parts of the body.

  • This may be caused by a number of factors including injury of the nerves, damaged blood vessels, lifestyle factors, and heredity.

Some Noticeable Symptoms

Symptoms of diabetic neuropathy may not be noticeable initially but may include the following:

  • Bowel movement problems (either constipation or diarrhea)
  • Lowered blood pressure
  • Tingling or numbness in the extremities
  • Nauseaurinal problems
  • Muscle weakness

Things To Remember

In addition to diabetes, other diseases such as vitamin B or folate deficiency and thyroid disease may trigger the numbness in your feet. Some medications may also have numbness as a side effect.

  • If you feel that these symptoms are true in your case, consult a physical immediately and take appropriate measures.

Conclusion

​In some short words

The sensation of numb feet when you run is not as unique as you may think. As we have learned, the condition may be caused by five main factors.

  • First, your sciatic nerves may be compressed leading to restricted blood flow and consequent numbness.
  • Second, you may be experiencing foot trauma because you went back to running too soon after injury and your nerves haven't fully recovered.
  • Third, your shoes may be too tight causing restricted blood flow and the tingling sensation.
  • Fourth, your foot structure may be the cause especially if you are flat footed.
  • Lastly, the numbness may be a result of a disease such as diabetes.

Once you identify the possible cause for your numbness when you run, take decisive steps to correct the issue. Remember that the faster you identify and correct your condition, the lower the chances of your condition from worsening.
