I have similar numbness in feet and sometimes lower legs. Likely due to nerve damage from being pre-diabetic. Left foot is better than the right. Sometimes my feet are like ice blocks. Not much in the way of pain tho. Sometimes my slippers or Sorel boots makes the toes in my right foot ache. I take PreGabalin which controls itching in my legs and elsewhere. My feet aren't constantly numb, but I don't think that any of my meds are helping numbness however. It seems that every malady that I have is complicated by something else.
