Numbness in the Feet. Numbness in the feet is a loss of sensation or feeling in the feet, as a result of improper communication between the nerves and the central nervous system. Commonly foot numbness is attributed to a blood shortage in the foot. This occurs when someone is sitting cross-legged for an extended amount of time.
TIngling in the feet can be caused by a variety of conditions. In general, it is important to rule out serious causes of the tingling--so I would strongly recommend that you see your primary care doctor to evaluate this condition. In general, the tingling sensation in your feet could represent a neuropathy--which is defined as damage to the nerve. Neuropathy can have many causes--the first thing to rule out is nerve impingement. For example, back problems can pinch a nerve that causes numbness or tingling in the legs.
