I am 70, male, married and in excellent health. 6 foot 2, 200 pounds. Working out three times a week on weights and swimming. Mainly sugar free diet. Lots of salads. Just recently experiencing pain in feet, mostly left foot. This pain is needle-like and occurs on top center, sometimes heal, sometimes small toe. Not ache, but more pinpoint burning. Recent visit with optometrist, with full set of tests, including for glaucoma, showed normal. At this point, no other associated symptoms.
