Slight numbness in the toes both feet ?

Hi mjr, of course diabetic neuropathy is the first cause that comes to mind but you know you need to see your doctor who will examine your feet.  When I googled for numbness of toes, I found this among many other sites:

Has your doctor ever done the prong test on your feet?  It's like a tuning fork that is placed on your foot or toe and you tell the doctor when you stop feeling the vibration? 

Yes, go see your doctor about it.  It may be something else, so it's better to know for sure what it is.  Good luck.
