Sudden, unexplained foot pain may be caused by irritated or damaged nerves.
6. Slow-Healing Cuts
High blood sugar affects blood flow and slows down the healing process.
If small cuts or blisters take a long time to heal, it may be a warning sign.
7. Dry, Cracked Skin
Diabetes can affect sweat glands, causing severely dry, flaky, or cracked skin on the feet.
8. Foot Swelling
Poor circulation and fluid retention — both linked to diabetes — can cause swelling in the feet and ankles.
9. Frequent Foot Cramps
Low circulation or nerve dysfunction due to high blood sugar can trigger cramps, especially at night.
