Why does type 2 diabetes cause numbness and tingling?

Diabetes-related peripheral neuropathy often starts gradually in the toes and feet and can later involve the hands. Sensations may include pins and needles, burning, electric-shock pain, reduced feeling, or unusual sensitivity to touch. Loss of feeling can make a blister, cut, or pressure point easier to miss. Numbness and Tingling is a very common presentation of Type 2 Diabetes, yet it can also be caused by a trapped nerve, vitamin deficiency, alcohol use, some medicines, or other neurological conditions.

Tell your clinician about new or changing sensations rather than waiting for your next scheduled review. Check both feet daily, including the soles and between the toes, for cuts, blisters, redness, swelling, or skin changes. Wear shoes that fit well and avoid walking barefoot. A clinician can assess sensation, pulses, skin, medicines, blood glucose management, and alternative causes. They can also discuss symptom relief and foot-care support.

Seek urgent assessment for a foot ulcer, spreading redness, warmth, swelling, discharge, blackened skin, or a wound you cannot feel. Get emergency help for sudden numbness or weakness on one side of the body, facial drooping, speech difficulty, or a severe sudden headache. Those abrupt neurological symptoms require immediate evaluation.

Could this be diabetic neuropathy or another nerve problem? What should I look for during daily foot checks? How can I improve blood glucose management safely? Which treatments could help burning, sleep disruption, or pain?
