I get it too... varies on sensitivity.... I've got used to it now, though. I've tried to explain some of the sensations to friends... one strange feeling is almost a remembrance of childhood...

When I was a child we would go walking across the fields, in our wellington boots. Anyway, often we would walk through puddles that were much deeper than we thought... and the water would rise so high it filled up the boots.

So you ended walking a fair way with cold water slooshing around your calves... and then once you'd emptied them, you still had to walk along with cold, wet calves all the way home.

I get a lot of that sensation... I call it getting the wellies... at first it was very disconcerting, but now its just there.

I hope yours clears up soon. Good luck.
