Tingling in Feet

Diabetes & Blood Sugar

If this is an emergency, call 911 now. This tool is for general information, not emergency guidance. If you're having severe symptoms, don't read this — get help.

What the internet says

Peripheral neuropathy. Diabetic nerve damage. Spinal stenosis. Multiple sclerosis. Blood clot.

What it probably actually is

Sitting cross-legged or with poor circulation for too long. Sleeping in an awkward position. B12 deficiency (extremely common, especially in older adults and those on metformin). Morton's neuroma (thickened nerve tissue in foot). Tight shoes compressing nerves.

🧠 The full picture

Temporary tingling from sitting weird goes away in seconds. Persistent tingling in feet that's always there, especially in diabetics, is worth a nerve check. But most people experience positional tingling regularly and it means nothing.

⚠️ When to actually call your doctor

These are real red flags. If any of these apply, don't wait.

You have diabetes and this is new — peripheral neuropathy check
Tingling progresses up the legs over days or weeks
Accompanied by weakness in legs
Burning pain in feet that's persistent
One foot only, with leg pain (possible circulation issue)
