Probably nothing to do with it, but I sometimes get one finger a
different colour and odd and wondered if it is to do with diabetes
stuff. But I don't really want to know, and if it starts to bug me
more seriously, like also head dizziness and nearly fainting, I tend
to just see to watch to not live on coke-chocolate diet too much
for a while till it is gone, and then don't care again.
