Why Do My Feet Go Numb When I Exercise?

Foot numbness or tingling after exercise is a common reason for referral to a sports medicine specialist, according to Dr. Russell O’Connor on Ecay Business. This condition can be caused by several things, including muscle and nerve conditions as well as other medical conditions, such as diabetes and central nervous system disorders.

Foot tingling or numbness with exercise is common for athletes and casual exercisers, according to JillianMichaels.com. One possible cause is footwear that is too tight or uncomfortable during exercise. Shoes that are too narrow or short in the box section are particularly common culprits of a numb sensation during or after exercise. Diabetes is also commonly associated with foot numbness during exercise or long periods of standing. The illness causes nerve damage, known as a condition called neuropathy, which results in numbness and tingling of the extremities.

Fluid buildup or swelling sometimes occurs within one of more of the body's muscle compartments during exercise, according to JillianMichaels.com. This phenomenon is called compartment syndrome. Although compartment syndrome is more common in the arms and lower legs, it often manifests in the toes as well. This can be a symptom of trauma from a stress injury or repetitive exercise, and it may require a change in workout regime to correct.
