Tingling feet can be caused by a wide variety of conditions and circumstances. Some of the most common causes are pinched nerves, lack of blood supply, certain medications, and some medical conditions. Nerve damage and repetitive trauma to the feet or legs could also result in a tingling sensation in the feet. Frostbite, a vitamin deficiency, and poor circulation are some other common causes of tingling feet.
One of the most common causes of a foot "going to sleep", a pins and needles feeling or numbness, is a lack of blood supply to that area. This generally is caused by poor circulation as a result of blood being cut off to the feet or pressure being placed on the nerves. When people sit or stand in one position for a long amount of time, the blood supply to the feet may be compromised in some way.
Sitting with the legs crossed or standing in such a way that prolonged pressure is put on the feet might result in numbness or tingling in the feet. Generally, a numbness results when the blood is not circulating properly and is being cut off. A tingling sensation will generally occur once blood begins circulating at a normal level.
Repetitive trauma or excessive impact on the nerves of the feet could result in a pins and needles sensation as well. This could be the result of strenuous exercise, jumping, or putting excessive pressure on the tendons, ligaments, and nerves of the feet or legs. Wearing shoes that are too tight can also cause tingling feet.
Certain medical conditions may lead to foot numbness or a tingling sensation. One of the most common conditions that can cause tingling feet is diabetes. Individuals with diabetes often experience inflammation or neuropathy, which both lead to a numbness and tingling in the feet. Other conditions that may affect the nerves of the feet include kidney disease, an underactive thyroid, and autoimmune diseases. Many spinal cord and back problems can also result in tingling feet.
Tingling feet might be the result of a vitamin B deficiency, excessive consumption of alcohol, and certain toxins. Some types of medications can also be the cause of a tingling sensation in the feet. Drugs taken to prevent seizures, some cancer medications, and AIDS treatments can cause tingling feet. The nerves of the feet can be damaged by some chemicals and toxins that may be put into the body, often resulting in a tingling sensation.
