There are many reasons why a toe might go numb and anyone with a numb toe should see a doctor for a proper diagnosis as numb toes most often mean that there are blood vessels and nerves in the foot that are experiencing problems. When people experience numbness in their toes, they often experience tingling as well, which is called paresthesia of the toes.
Many times the numbness of toes is a consequence of wearing shoes that are too tight around the toes or that press down on the toes. This causes the nerves in the toes to be compressed leading to numbness. It can also happen when a person sits on their foot for too long. However, numbness can be a symptom of much more serious problems.
People with diabetes and with peripheral vascular disease can experience numbness if they have improper circulation of blood within the foot nerves, as stated by MedicineNet. There can also be skin problems, such as burns or radiation treatment, that will cause numbness in the toes and feet. Both Lyme disease and shingles can also cause numbness.
Brain conditions are serious and life-threatening in many cases. Numbness in areas of the body is one of the first signs of brain problems such as migraines, anxiety, hyperventilation and more debilitating diseases such as multiple sclerosis, as stated by The Dr. Oz Show.
