Hi Anthonie
Very intense explanation. But I don't beleive it is quite that complicated. It's just a matter of blood flow being
obstructed. Once you move around it comes back again. I find your hypothesis interesting though and it does make sense that
this may in fact occur if the cells do not receive oxygen from the blood..
Take care
