Neuropathy & Numbness
How Do You Treat Neuropathy?
Amarish Dave, DO explains the two goals of neuropathy treatment: identifying the underlying cause of nerve damage and treating the symptoms it causes.

Why Is My Foot Numb or Tingling?
Numbness or tingling in a foot can happen for many reasons. The location, pattern and associated symptoms provide important clues about where the problem is occurring.
Written and medically reviewed by Amarish Dave, DO, board-certified neurologist. This page is educational and does not replace an individual medical evaluation.
Possible neurological causes
- Peripheral neuropathy
- A pinched nerve in the lower back
- Sciatica or lumbar radiculopathy
- Compression or injury of an individual nerve in the leg or foot
- Diabetes
- Vitamin deficiencies, particularly vitamin B12 deficiency
- Certain medications or toxins
- Less commonly, disorders involving the spinal cord or brain
Could it be neuropathy?
Peripheral neuropathy often begins in the toes or feet and can cause numbness, tingling, burning, electrical sensations or decreased sensation. When neuropathy affects both feet, symptoms often gradually develop in a similar pattern on each side and may progress upward over time.
Learn more about what neuropathy is and how it is evaluated and how neuropathy is treated.
Could it be a pinched nerve?
A nerve irritated or compressed in the lower back can also cause numbness or tingling extending into the leg or foot. The distribution may follow a particular nerve root and can sometimes occur with back pain, shooting leg pain or weakness.
Neuropathy and a pinched nerve can produce similar symptoms but have different causes and may require different evaluations and treatments. Our back and neck nerve evaluation page explains how pinched nerves and radiculopathy are assessed.
How does a neurologist evaluate foot numbness?
Evaluation starts with the history and neurological examination. Depending on the symptoms, testing may include:
- Blood tests
- Nerve conduction studies
- EMG
- MRI or other imaging when a pinched nerve or another structural problem is suspected
Testing is individualized—not everyone with foot numbness requires every test.
When can numbness be an emergency?
Gradual tingling in the feet is different from sudden neurological symptoms. Seek urgent or emergency medical evaluation for sudden numbness, particularly when accompanied by:
- Weakness or paralysis
- Facial drooping
- Difficulty speaking
- Sudden severe imbalance
- Loss of bladder or bowel control
- Numbness involving the groin or saddle region
- Rapidly progressing weakness or numbness
Sudden symptoms are different
Sudden or rapidly progressive neurological symptoms may require urgent medical evaluation—do not assume they are a routine neuropathy.
Key takeaways
- Foot numbness and tingling have many possible causes—the pattern provides important clues.
- Neuropathy often starts in both feet and gradually progresses upward.
- A pinched nerve in the lower back can cause one-sided numbness or tingling following a nerve root.
- Diabetes and vitamin B12 deficiency are common, treatable contributors.
- Evaluation is individualized: history, examination, and only the tests likely to help.
- Sudden numbness with weakness, speech difficulty, or loss of bladder or bowel control is an emergency.

Frequently asked questions
- Why are my toes numb?
- Numb toes are commonly caused by peripheral neuropathy, which often begins in the toes and feet. Other causes include a pinched nerve in the lower back, diabetes, vitamin B12 deficiency, certain medications, or compression of an individual nerve. The pattern and associated symptoms help identify the cause.
- Why is only one foot tingling?
- Symptoms affecting only one foot suggest a problem on that side—such as a pinched nerve root in the lower back, sciatica, or compression of an individual nerve in the leg or foot—rather than a length-dependent neuropathy, which usually affects both feet in a similar pattern.
- Can neuropathy cause numb feet?
- Yes. Peripheral neuropathy often begins in the toes or feet and can cause numbness, tingling, burning, electrical sensations or decreased sensation. When it affects both feet, symptoms typically develop gradually in a similar pattern on each side and may progress upward over time.
- Can a pinched nerve in my back make my foot numb?
- Yes. A nerve root irritated or compressed in the lower back can cause numbness or tingling extending into the leg or foot, sometimes with back pain, shooting leg pain or weakness. Neuropathy and a pinched nerve can feel similar but have different causes and treatments.
- Can diabetes cause tingling in the feet?
- Yes. Diabetes and prediabetes are among the most common causes of peripheral neuropathy, which typically begins with tingling, burning or numbness in the feet. Blood testing is part of the evaluation, and glucose control is central to treatment.
- What tests are used to diagnose foot numbness?
- Evaluation starts with the history and neurological examination. Depending on the symptoms, testing may include blood tests, nerve conduction studies and EMG, and MRI or other imaging when a pinched nerve or another structural problem is suspected. Testing is individualized—not everyone needs every test.
- When should I see a neurologist for numbness or tingling?
- Consider an evaluation when numbness or tingling persists, spreads, is accompanied by weakness or balance problems, or interferes with walking or sleep. Sudden numbness—especially with weakness, facial drooping, difficulty speaking, severe imbalance, or loss of bladder or bowel control—needs urgent or emergency evaluation.
