Before I start I HAVE NEVER HIT MY HEAD OR FALLEN HARD ENOUGH TO CAUSE THIS. I'm a 15 yr old girl and as long as I can remember I've had a dent on the side of my head. It's gotten extremely big and there's random dents covering my head now, not as big as the one on my right side but still big enough to feel. It's somewhat swollen around the ridges and if I press down hard enough, it hurts. It never bothered me until I was 13, I got a X-ray but they said it was nothing, a couple of months ago I told my doctor and he told me to get a MRI, I got it done and they said it was nothing. My mom and the people that did my first x rays say it's just my brain growing and that explains why my dent is growing but I don't think so. Can someone explain what's happening?????
