HI, my sis woke up with an indention in her head. She describes it as being as long as her little finger. She hasn't hit her head or had any injuries, just noticed it today. Do you know what could cause this? She hasn't mentioned any other problems. Just the dent it's scary to her. She doesn't have any heath insurance so afraid to got get test done because will bankrupt her. I wish we had medical like Canada. There's just way to many of us out there with no insurance. And they only have count of a few. I bet there's millions more they don't have on the books that are without it as well. Anyway, any help with the indention will be greatly appreciated. Thank you kindly
