CDC diabetic peripheral neuropathy tingling feet symptoms foot care

Tingling in the feet of a person with diabetes is commonly a sign of diabetic peripheral neuropathy. Persistently high blood glucose can damage the small blood vessels and nerves, especially the longest nerves supplying the toes and feet.
Typical features include:
  • Tingling, pins-and-needles, burning, or electric-shock sensations
  • Symptoms beginning in both feet and progressing upward in a “stocking” pattern
  • Pain or sensitivity to light touch, often worse at night
  • Later, numbness and reduced ability to feel heat, injury, or pressure
This matters because numb feet can develop unnoticed cuts, blisters, burns, or ulcers, which may become infected. Diabetes is a leading cause of peripheral neuropathy. Harrison’s Principles of Internal Medicine, section “Diabetic Neuropathy.”
What to do
  • Arrange a medical review for a foot and nerve examination. Other causes, such as vitamin B12 deficiency, thyroid disease, alcohol use, medication effects, kidney disease, or a pinched nerve, may also need consideration.
  • Keep blood glucose, blood pressure, and cholesterol within the targets set by the clinician.
  • Check both feet every day, including between the toes. Use well-fitting footwear and avoid walking barefoot.
  • Have at least an annual comprehensive diabetic foot exam, or more often if neuropathy is present. The American Diabetes Association guidance lists tingling as a common symptom and recommends regular foot checks.
Seek urgent care if there is a new foot wound, redness, warmth, swelling, black/blue discoloration, fever, or sudden one-sided weakness or numbness.
