Pins and needles in your feet. Burning that shows up at night. A numb patch that never quite wakes up. Plenty of people shrug these off as circulation, tight shoes, or age — but they can be signs of peripheral neuropathy: damage to the nerves that carry signals between your spinal cord and your hands and feet.
What’s actually happening
Your peripheral nerves are long, delicate wiring — the ones to your toes are the longest in your body, which is why symptoms usually start in the feet. When those nerves are damaged or starved, they misfire (tingling, burning, electric jolts) or go quiet (numbness). Both matter, and the quiet kind is sneakier: you can’t feel what you can’t feel.
Common causes
- Diabetes and chronically high blood sugar — by far the most common driver.
- Vitamin deficiencies, especially B12.
- Certain medications, including some chemotherapy drugs.
- Pressure on a nerve along its path — from the spine, or at pinch points like the carpal tunnel.
- Alcohol, thyroid, and kidney issues, among others — which is why the cause deserves a real workup, not a guess.
Why early matters
Numb feet change how you walk and balance before you consciously notice — raising the risk of falls, and of injuries you don’t feel happening. A blister that goes unnoticed on a numb foot is how small problems become serious ones, especially with diabetes. Caught early, the underlying drivers are far more manageable.
Worth doing now
- Check your feet daily for cuts, blisters, or pressure spots you may not feel.
- Know your blood sugar. Ask your doctor about an A1C test if you haven’t had one.
- Practice balance a few minutes a day — the single-leg test is a good start, near a counter.
- Track the pattern: when symptoms show up, both sides or one, what helps.
If these symptoms sound familiar, don’t wait them out — start with a thorough evaluation. Our $99 new patient exam and TRUScan establishes a baseline of how you’re moving and functioning, and we’ll be honest about what your case needs, including when it calls for medical workup alongside functional care. One emergency to know: sudden numbness or weakness, especially on one side of the body, can be a stroke — call 911 immediately.
