burning feeling in foot.....

I'm feeling a heat in the left foot just for seconds at a time. What does that mean?

I have the same thing. What you describe sounds exactly like me. I am in my early 60s, and I know of no health problems except high blood pressure. I do not take medicine for high blood pressure, but I can get it down easily by eating beets. I discovered this by reading about herbal medicines on the internet. Then I tried it. It works so beautifully for me, but I am not you. I don't know if it would work for you. I have not tested this extensively, but I notice that when I eat beets now, the burning goes away for a few hours.
