Treatment at Balance Foot & Ankle: Diabetic Foot & Circulation Screening →

Quick Answer

Diabetic peripheral neuropathy is nerve damage from prolonged hyperglycaemia, causing burning, tingling, numbness, or loss of protective sensation in the feet. It will not reverse without addressing glucose control. Daily foot checks, proper footwear, and annual monofilament testing prevent ulceration.

Peripheral neuropathy — dysfunction of the peripheral nerves producing numbness, tingling, burning pain, or weakness in the feet and lower legs — is one of the most common conditions encountered in podiatric practice. Diabetic peripheral neuropathy alone affects 50% of patients with long-standing diabetes; but the podiatrist must recognize that neuropathy in the foot patient is not always diabetic in origin and requires systematic evaluation to identify treatable etiologies, guide risk stratification, and determine when neurological referral is appropriate.

Clinical Evaluation and Screening

The standard clinical screening tools for sensory neuropathy in the podiatric examination: Semmes-Weinstein 10g monofilament testing at 4–6 plantar foot sites (inability to detect 10g pressure = loss of protective sensation, the key threshold for diabetic foot ulcer risk); vibration perception threshold with a 128Hz tuning fork at the hallux; and proprioception testing at the hallux IP joint. Neuropathy symptom patterns that suggest non-diabetic etiology: asymmetric presentation, prominent motor weakness, rapid progression, neuropathic pain out of proportion to sensory loss, or onset before age 40 without diabetes — these warrant expanded workup including laboratory screening (CBC, CMP, TSH, B12, folate, SPEP for paraprotein, VDRL, anti-Ro/La, anti-nuclear antibodies).

Advanced Diagnostic Testing

Nerve conduction studies (NCS) and electromyography (EMG): the standard electrodiagnostic evaluation for peripheral neuropathy — identifies whether the neuropathy is axonal (amplitude loss on NCS, suggesting metabolic, toxic, or genetic causes) or demyelinating (conduction velocity slowing, suggesting inflammatory neuropathy such as CIDP that responds to treatment). Skin punch biopsy with intraepidermal nerve fiber (IENF) density analysis: a 3mm punch biopsy of the distal leg skin — stained for PGP9.5, a pan-neuronal marker — allows quantification of small unmyelinated C-fiber density. IENF density is reduced in small fiber neuropathy (SFN), which is frequently normal on standard NCS because small C-fibers are not measured by electrodiagnostics. SFN produces burning pain and autonomic dysfunction without NCS abnormalities. Dr. Biernacki at Balance Foot & Ankle performs neuropathy screening at every diabetic foot examination and coordinates neurological referral when non-diabetic neuropathy is suspected.

When to See a Podiatrist

Many foot conditions can be managed conservatively at home, but some require professional evaluation. See a podiatrist promptly if you experience:

  • Pain that persists for more than 2 weeks despite rest
  • Swelling, redness, or warmth that isn’t improving
  • Numbness, tingling, or burning in the feet
  • A wound or sore that is not healing within 2 weeks
  • Any foot concern if you have diabetes or poor circulation
  • Nail changes that suggest fungal infection or other problems

At Balance Foot & Ankle, our three board-certified podiatrists — Dr. Tom Biernacki, Dr. Carl Jay, and Dr. Daria Gutkin — provide comprehensive foot and ankle care at our Howell and Bloomfield Township offices. Most insurance plans are accepted.

Differential Diagnosis: What Else Could It Be?

Several conditions share symptoms with Diabetic Neuropathy and are commonly misdiagnosed in the first office visit. Considering these alternatives is part of every Balance Foot & Ankle exam:

  • Tarsal tunnel syndrome. Burning radiating into the arch with positive Tinel’s at the medial ankle.
  • Peripheral artery disease. Pain with walking that resolves with rest, weak pulses, hair loss on toes.
  • Lumbar radiculopathy. Symptoms following a dermatome, often with back pain — MRI of spine, not foot.

If your symptoms don’t fit the textbook pattern, ask your podiatrist which differentials they ruled out — that conversation often shortcuts months of trial-and-error treatment.

In Our Clinic

Diabetic neuropathy patients in our clinic often don’t realize they have it until we put a 10-gram Semmes-Weinstein monofilament to the plantar foot and they can’t feel it. Many arrive for an unrelated concern — an ingrown toenail, a callus — and we catch the neuropathy on screening. The conversation then shifts: we need to discuss daily foot inspections, appropriate footwear, the urgency of any blister or open area, and the timing of vascular referral if pulses are diminished. Comprehensive diabetic foot exams are covered by Medicare annually. If you have diabetes, we want to see you once a year even if nothing hurts.

Most Common Mistake We See

The most common mistake we see is: Stopping B-vitamin supplementation as soon as symptoms improve. Fix: maintain supplementation for 6-18 months alongside strict glucose control.

Warning Signs That Need Same-Day Care

Seek immediate evaluation at Balance Foot & Ankle if you experience any of the following:

  • Sudden loss of sensation on one side
  • Wound on the foot not felt by the patient
  • One-sided symptoms (rule out compression)
  • Back pain plus leg symptoms (possible radiculopathy)

Frequently Asked Questions

Can a podiatrist help with neuropathy?
Yes. Podiatrists specialize in foot neuropathy management including nerve testing, diabetic foot monitoring, custom orthotics for protection, and therapies like MLS laser treatment to improve nerve function.
What does neuropathy in feet feel like?
Peripheral neuropathy typically causes tingling, numbness, burning, or sharp shooting pain in the feet. Symptoms often start in the toes and progress upward. Some patients describe it as walking on pins and needles.
Is foot neuropathy reversible?
It depends on the cause. Neuropathy from vitamin deficiencies or medication side effects may be reversible. Diabetic neuropathy is typically managed rather than reversed, but early treatment can slow progression and reduce symptoms significantly.
