I'm 24 and in relatively good shape--I'm thin, eat a lot of vegetables and fruits, work out semi-regularly. To my knowledge, I have no family members with diabetes. However, I eat a lot of candy--probably 2 lbs of Reese's Pieces a week. It isn't affecting my weight but I have been experiencing spots of numbness, at different times, in my shoulders, feet, arms, hands, calves and thighs. It seems to correlate with my recently increased candy-eating. It's not like when your foot falls asleep; it has a throbbing quality, though it's painless . Am I pre-diabetic?
