Im 18 years old and i have 2 dents on my head, one on the left side and one on the right. Ive had them for i think quite a while, all i really know is i had a habit of falling down stairs when i was younger and i used to get migraines, about 4 years ago i went to see a specialist for them and they said i would out grow them which i did, and during one of the visits they did a cat scan on my brain to make sure there wasnt anything wrong, test came out negative. Could falling down stairs cause my skull to have dents?
