What Causes Numbness In The Toes While Suffering From Diabetes?

Hi, I am a female age 76, 5 3 , weight of 120, active & feel great with no health issues. I do not take any prescription medications. I do take several vitamins each morning & a 50mg water pill each day (all over the counter.) I do not have diabetes. My question is this: on both feet, all my toes to approx. 1/4 of my fee (from the toes) always feel very numbish. Especially when I m laying in bed during the night. I realize that someone who has diabetes will have this issue - but I don t have diabetes, so what would be any other reasons for this to be happening? This has been going on for approx. a year & started out with one toe on one foot (left foot - next to little toe....which I had badly stubbed months before so thought it was a damaged nerve from that) - but then to my surprise, it spread to the other toes as time went on & now, the other foot & toes are doing the same thing. I have not gone to a doctor about this yet because I ve been thinking it will run it s course soon & go away. For now....I m hoping you can give me some input as to why this is happening. Thank you.
