Diabetic Nerve Pain (Peripheral Neuropathy)

Diabetes can cause pain in many areas of the body, but by far the most common pattern is a gradual, creeping burning in the feet. Patients describe it vividly: difficulty walking on certain surfaces like the shower floor, a sensation of walking on marbles, or feet so sensitive that the weight of a bedsheet at night is painful. This condition is called diabetic peripheral neuropathy — and almost every form of it is worse at night.

Less commonly, diabetes causes pain in the abdomen or trunk (thoracoabdominal neuropathy) or affects a single nerve (mononeuropathy), classically one of the nerves that moves the eye.

What causes it?

Years of elevated blood sugar damage both the nerve cells themselves and the small blood vessels that feed them. The longest nerves in the body — the ones running to the feet — are damaged first, which is why symptoms almost always start in the toes and feet and work upward in a "stocking" pattern.

How is it treated?

The first goal is always tight blood sugar control, because that's what prevents further nerve damage. Nothing we do for the pain matters as much as protecting the nerves you still have.

For the pain itself, treatment has improved dramatically over the past two decades:

Nerve-pain medications are the foundation. The most effective first-line options are gabapentin and pregabalin — medications our practice was among the first in the country to use for pain — and duloxetine, an antidepressant-class medication that works on pain pathways directly. Taking one of these does not mean you're being treated for depression or seizures; they calm the abnormal nerve firing that causes burning pain. Older tricyclic antidepressants remain useful for some patients.

Ordinary pain relievers usually disappoint. Anti-inflammatories and acetaminophen do little for nerve pain, and diabetics need particular caution with anti-inflammatories because of kidney and stomach risks. Opioids are not an appropriate long-term treatment for diabetic neuropathy — the evidence is clear that risks outweigh benefits.

Topical treatments help selected patients. Prescription-strength capsaicin patches and lidocaine preparations can reduce pain in a targeted area without body-wide side effects.

Spinal cord stimulation for resistant cases. For patients whose pain doesn't respond to medications, spinal cord stimulation is now an FDA-approved treatment specifically for painful diabetic neuropathy — a genuine advance for people who had run out of options.

No treatment is curative, but the honest good news is this: most patients with diabetic nerve pain can get meaningful relief with the right combination of therapies, and sleep — usually the first casualty — is often the first thing we can give back.

When to be seen

If you're diabetic and your feet burn, tingle, or feel numb, don't wait for it to "settle down." Earlier treatment works better, and numbness carries its own risks — injuries you can't feel become ulcers you can't afford. Call Newport Pain Management at (949) 759-8400 for an evaluation.
