I noticed small bruises on the back of my hands about a month ago, with no recollection of knocking anything and no pain. Today, I was helping my husband move a piece of furniture and then I saw this big swelled up bruise on the back of my hand. It's not painful unless I press on it, but looks like the largest vein on the back of the hand has burst and formed a hematoma. I put an ace bandage on to keep the swelling down. Can lifting something heavy cause a hand vein to burst? Should I be worried about other veins popping?
