I was in a car accident and my whole left side of my body hit the driver door, within a short time I noticed a bruise on my left temple, well I thought it was a bruise, it is a vein and that area is sunken in and also getting headaches. When I sleep on my left side, I shortly feel the pressure that makes me uncomfortable and end up turning on my right side to fall asleep. Can anyone tell me ......What's going on?
