I have not read boojum's response yet...that takes a while, but it sounds like a popped vein. That happened to me. When you get an injection or a blood draw, sometimes the tech can accidentally stab through both sides of the vein, which causes bleeding into the surrounding tissue & sometimes swelling and bruising. It's uncomfortable and mildly painful but not serious & should go away after a day or two.
IIN for my skin to swell days after being injected?
