Peripheral neuropathy is damage to the peripheral nerves — the vast network that carries signals between your brain and spinal cord and the rest of your body. When those nerves misfire or stop working properly, the result is the familiar cluster of symptoms: numbness, burning, tingling, and sharp or shooting pain, most often beginning in the feet and hands. It's common, it has many possible causes, and — this is the part worth holding onto — the pain it produces is very treatable.
What peripheral neuropathy feels like
Most people notice sensory symptoms first, and they tend to follow a recognizable pattern. Burning, tingling ("pins and needles"), numbness, or an electric, shooting pain typically starts in the toes and soles and can spread upward over time in what's often called a "stocking and glove" distribution — feet first, then sometimes the hands (NINDS peripheral neuropathy fact sheet). Symptoms are frequently worse at night, which is why so many people first describe the problem as burning or crawling feet that won't let them sleep.
Neuropathy can affect three broad categories of nerves. Sensory nerves produce the numbness, pain, and abnormal sensations most people recognize. Motor nerves, when involved, can cause muscle weakness, cramping, or an unsteady gait. Autonomic nerves — the ones that run automatic functions — can, less commonly, affect blood pressure regulation, digestion, sweating, and bladder control (NINDS peripheral neuropathy fact sheet). A key and sometimes overlooked point: numbness is not "better" than pain. Loss of protective sensation means an injury to the foot can go unnoticed until it becomes serious.
What causes it
Peripheral neuropathy is not one disease but a shared endpoint of many different conditions. By a wide margin, the most common cause is diabetes. Persistently elevated blood sugar damages the small nerves over years, and because the longest nerves reach the feet, that's where diabetic neuropathy usually announces itself (diabetic peripheral neuropathy, StatPearls / NCBI). Diabetic neuropathy alone affects a large share of people with long-standing diabetes.
Beyond diabetes, common causes include:
- Chemotherapy — several cancer drugs are toxic to nerves and can leave lasting numbness and pain in the hands and feet.
- Heavy alcohol use and nutritional deficiencies — particularly low vitamin B12, which nerves depend on.
- Physical injury or compression — trauma, surgery, or a pinched nerve.
- Autoimmune and inflammatory conditions, thyroid disease, kidney disease, certain infections, and some inherited disorders.
In a meaningful number of cases no cause is ever pinned down, which is called idiopathic neuropathy. Identifying the driver matters because treating it — better blood-sugar control, correcting a deficiency, relieving a compression — is often what determines whether the neuropathy stabilizes or keeps advancing.
If your symptoms match a specific cause, we cover several in more depth: diabetic neuropathy in the feet, chemotherapy-induced neuropathy, and burning feet at night.
When to see a specialist
Occasional tingling isn't an emergency, but there are clear signals that it's time for a professional evaluation rather than waiting it out. Consider seeing a specialist if:
- Numbness, burning, or shooting pain is spreading from the toes upward or appearing in a new area.
- Symptoms are worsening or increasingly disrupting your sleep or daily activities.
- You have diabetes and any foot numbness — because loss of sensation raises the risk of unnoticed injuries, blisters, and ulcers that can become dangerous.
- You notice weakness, balance problems, or frequent stumbling.
- Over-the-counter measures and, in particular, prescription medications aren't controlling the pain.
An evaluation typically starts with a history and neurological exam and may include bloodwork to look for treatable causes and, in some cases, nerve testing. The goal is twofold: identify and address any underlying driver, and build a plan to control the pain itself.
What treatment looks like — and why there's real optimism
Here's the honest, hopeful framing. Established nerve damage often can't be completely undone, but neuropathic pain is one of the more treatable forms of chronic pain, and the toolkit has genuinely improved.
Treatment usually starts with addressing the cause and trying medications — gabapentin, pregabalin (Lyrica), duloxetine, and others. These help some people meaningfully. But they have a real ceiling: across neuropathic pain conditions, the number needed to treat for worthwhile relief is generally between 4 and 10, and side effects lead many people to stop (Cochrane review of pregabalin for neuropathic pain). A frequent goal for patients is to avoid depending long-term on these medications or on opioids.
When pills fall short, that's exactly when minimally invasive, reversible options deserve a look. Nerve stimulation — placing a small device that quiets pain signals — can be trialed for several days before you commit to anything permanent, so you feel the relief firsthand first. For painful diabetic neuropathy specifically, a randomized trial found 79% of stimulation patients were responders versus 5% on medication alone, and the approach is FDA-approved for that use (randomized clinical trial, PMC/NIH). For pain limited to one nerve region, a related peripheral-nerve approach helps roughly two-thirds of appropriately selected patients (systematic review of peripheral nerve stimulation).
One safety note if you're already on medication: never stop or cut back gabapentin or pregabalin on your own or abruptly — they should be tapered slowly under your prescriber's guidance to avoid withdrawal effects.
