A few days a go while doing normal evening routine at home, the back of my right hand itched. As you do gave it a light scratch with my left hand and carried on. Within seconds all the veins in my right hand swelled up greatly to form like one big mass. It was soft and squidgy and dark blue all over. Went to bed after an hour of it looking the same.
Next 3 days I'm left with a black flat patch on the back of my hand.
Any ideas as to why this happened or has anyone had the same thing. Seems to trivial to ask Gp.
