VEINS BURSTING IN HANDS

Hi you should just see the ENORMOUS black bruise on the back of my hand. My knuckle itched yesterday, went to sort of scratch it but before I could do so the knuckle swelled up, stung, and bleeding started. In just two minutes there was a huge area of swelling/puffiness and a few hours later ALL the back of my hand was dark blue. I've had this finger popping thing for years on and off, once on the palm of my hand which was a big area and really nasty looking. I'm 69, eat very healthily, active, slim, brilliant cholesterol. Is anyone still on this site? GinB, Valeriejj53? I've just joined today and read every single post. Please please write to me if you are still on here.
