Whenver I walk distances my fingers swell up on both hands.
I've usually put it down to my rucksack pulling around my armpits & restricting circulation, but today I did 10 miles without the sack & the bloomin' things are more swollen than usual !
My Dad, who I was walking with, suggested it's lack of water, but I'd drunk one litre on the walk & there was nothing strenuous about the route.
Having been home for an hour they're starting to return to normal, but something's happenning while I walk and I want ot know what it is.
