Tingling or burning in the feet can feel stronger at night because there are fewer distractions. Some people describe it as pins and needles, crawling, burning, sharp pain, or numbness.
Diabetes can affect the nerves, especially in the feet. The American Diabetes Association notes that peripheral neuropathy symptoms, including burning or shooting pain, are often worse at night.
Foot tingling can also come from vitamin B12 deficiency, back problems, thyroid disease, circulation issues, or medication effects. Repeated symptoms should be checked.
5. Restless Sleep
Blood sugar changes can disturb sleep in different ways. High blood sugar may cause thirst and bathroom trips. Low blood sugar may cause sweating, sudden waking, anxiety-like feelings, or vivid dreams.
Restless sleep alone does not prove diabetes. But when poor sleep appears with thirst, frequent urination, tingling feet, or morning fatigue, blood sugar should be considered as one possible factor.
6. Blurry Vision at Night or in the Morning
