Need some advice. Took a shot in my calf about a week ago. I must of hit a vein or something. Leg is bruised from top of calf to bottom of ankle. Also swells up quite a bit after working all day,but swelling goes down after sitting down for a while. Do you think the blood will eventually disperse or do you think there is a chance it's still bleeding inside? It's been about a week since the injection and there was no blood when I pulled the needle out.
