Try reducing the blood pressure in your hands by running with them above your head. Even if it doesn't work you'll be running in a permanent victory salute, so win-win.
I get the hand swelling, not balloons, but they feel weird, I've always assumed it's from restricted circulation because of the angle of my elbow when I run, so when I start to feel it I straighten my arms and kind of wave them about... Will try the victory pose too.
