Numbness in the toes can be caused by nerve damage, injury to the foot or be a result of poor circulation due to diseases such as peripheral vascular disease or diabetes; low back pain associated with radiculopathy or pinched nerves can also generate toe numbness, according to MedicineNet. Generally, conditions that affect the blood vessels that transport blood to the foot or nerves runningthrough the foot can cause numbness.
There are other potential causes of toe numbness, notes Healthline. Spinal stenosis, which is a condition characterized by the narrowing and gradual compression of the spinal cord that can lead to nerve problems, can result in toe numbness. Mononeuropathy, which is a nerve condition caused by autoimmune disorders, nutritional deficiency or injury can also bring on numbness of the toes.
Hypoparathyroidism, in which the body fails to produce a sufficient supply of parathyroid hormone, can result in toe numbness. The autoimmune disease multiple sclerosis can also cause numbness in the toes.
Some conditions causing toe numbness are medical emergencies. One such condition is intracerebral hemorrhage, which occurs when blood bursts suddenly into the brain tissue, resulting in stroke-like symptoms. Vertebrobasilar circulatory disorder, which is caused by an insufficient supply of blood to the brain, is also a medical emergency, and toe numbness is a symptom to watch for.
