 [ Symptoms ] why do i get bronchitis every time i get a cold [ Disease ] unfortunately there is no way to tell you what is causing the numbness without a physical examination and possibly an x ray or some other diagnostic imaging many conditions could cause the symptom you are describing though the likely culprit is a compressed or pinched nerve even though you only wear low heels the shoes could be at fault however your best bet is to visit a doctor to get this checked out it is probably not anything serious but you do not want to permanently damage a nerve by ignoring the situation hope this helps
