I haven't said it sounds ridiculous. I haven't evennthought it sounds ridiculous. I've asked why. Nobody has answered the question yet. I would actually like to know why standing on a pillow has been suggested. Obviously the reason isn't obvious or I wouldn't have asked.
Why not? It doesn't sound any more ridiculous than the other suggestions! Could it (seriously) be to do with standing still? Have you tried/do you wear Birkenstocks/fitflops/MBT trainers? Might be good to keep the circulation moving by keeping the feet moving ?? I believe guardsmen and others who have to stand for long periods shift their weight imperceptibly by rocking forwards and backwards or foot to foot. I know it sounds silly too!
Have you tried raising your legs higher than the rest of your body? If you lie on the floor at right angles to the wall and rest your legs against the wall then the blood flow to your feet will be reduced. I think this is the most sensible solution.
I think your kitchen floor is too hot, Bags. Keep a special mat in the fridge for when you do the washing up. Alternatively, get someone else to do it!
