If you notice unusual changes in your feet—such as persistent numbness, tingling, burning, or slow-healing wounds—don’t ignore them. These symptoms can sometimes be linked to diabetes-related nerve or blood-vessel problems.
Here are 7 foot symptoms that may occur with diabetes:
- Persistent numbness – Reduced sensation, especially in the toes or soles, can be a sign of diabetic nerve damage.
- Tingling or “pins and needles” – A prickling sensation in the feet can occur when high blood sugar affects nerves.
- Burning or unusual pain – Some people experience burning, sharp, or shooting pain in their feet.
- Loss of sensation to temperature or touch – You may not notice heat, cold, or minor injuries as easily as before.
- Slow-healing cuts or sores – Diabetes can impair circulation and the body’s ability to heal wounds.
- Swelling or changes in the skin – Dry, cracked skin, discoloration, or swelling can accompany circulation or nerve problems.
- Frequent blisters, ulcers, or unexplained injuries – Reduced sensation can allow small injuries to worsen before you notice them.
Important: These symptoms do not automatically mean your blood sugar is high. Several other conditions can cause similar foot problems. The only way to know whether you have elevated blood glucose is through appropriate blood-sugar testing, such as a fasting glucose or HbA1c test.
