I had it, in my left hand and slightly on my left side.
Once I cut back on the carbs it went away took 2 or 3 weeks of very low carbs.
Over Xmas when I 'forgot' about carbs it came back in two fingers on my left hand.
I can only assume for me, there is a connection between what I eat and the feelings in my fingers.
I have read somewhere that hands are the easiest to repair, but I cant remember where I saw it so have nothing to back that up with.
I am hoping that with extra weight loss this year I will make a full recovery. I would say I am 90% better and if I had stayed on duty over December would possibly be fine now. I haven't done the very low carbs this year yet but I am still low.
