What is tingling in one foot?

Tingling in one foot can have a number of causes, including an injury, sitting in one position for a long period of time, or a circulation problem that impairs blood flow to the feet. Tingling in one foot can also be caused by nerve damage from extreme heat or cold or from toxic substances.

Alternatively, tingling in one foot may be caused by peripheral neuropathy, a disorder in which the peripheral nerves that relay signals between the body and the brain and spinal cord lose function. Peripheral neuropathy can be due to a number of specific diseases and disorders, including diabetes and alcoholism. In many cases, peripheral neuropathy has no known cause.

Depending upon the cause, tingling in your feet may be felt at rest or while walking or moving around. In some cases, tingling may occur in the foot only or it can be felt in other areas of your body as well. The duration and course of tingling in one foot can vary widely, depending on the underlying condition. Tingling in one foot caused by injury often has a sudden onset, while tingling resulting from peripheral neuropathy develops slowly and persists or worsens over time.

Seek immediate medical care (call 911) if a sudden foot tingling sensation is accompanied by numbness or weakness on one side of your body; a change in level of consciousness or alertness, such as passing out or unresponsiveness; or the worst headache of your life, as these can be signs of stroke.

If your tingling in one foot is persistent or causes you concern, seek prompt medical care.
