Numb Toes & Feet
Nerve problems in your feet can be caused by several metabolic issues, such as alcohol use, heavy metal exposure, hyperlipidemia and, most commonly, diabetes mellitus.
Numbness in feet and toes that is symmetrical is called poly-neuropathy. In previous years, diagnosis of poly-neuropathy was made by subjective, qualitative and indirectly quantitative techniques.
Today an indication of poly-neuropathy can be initially identified by subjective complaints as well as objective qualitative evaluation. These techniques include evaluating vibratory sensation, two-point tactile discrimination, warm-cold discrimination and protective sensorium. The most critical qualitative finding is that of protective sensorium. If protective sensorium is lost in your feet, then you will not know if an injury has occurred. Subsequent infection and tissue loss is a result, sometimes as severe as an amputation.
