I was pre-diabetic. I weighed 192 on a five foot one frame. I lost 65 pounds for BP, to avoid diabetes, and to take weight off my bad ankle. Have some kind of PN on my left foot going up my leg. I wonder if there is a connection too as this didn't happen to me until I lost the weight. However I did have two surgeries on that foot. Just throwing this out there, as I don't know what caused this either. ginnie
