Foot numbness may be caused by various factors, usually related to nerve compression or dysfunction. Common causes include: 1. Maintaining the same posture for a prolonged period, such as sitting for long durations or compressing nerves in the arms or legs during sleep, leading to temporary numbness. 2. Neuropathy, such as diabetic neuropathy, in which high blood sugar damages nerves, often causing numbness or tingling in the hands and feet. 3. Spinal problems, such as cervical spondylosis or lumbar disc herniation, which compress the nerve roots extending to the lower limbs. 4. Ischemic diseases, where poor blood circulation results in insufficient blood supply to the feet, potentially causing numbness. If foot numbness persists, worsens, or is accompanied by other symptoms such as pain or weakness, prompt medical attention is advised.
