If you look between my sons eyes you can see a bump there. He has had it since birth. The doctors think it is a cyst because it is mobile. It is really hard. Have any of you experienced this. He gets an ultrasound on the 8th over it. I a hoping it is nothing bad. They called me today to schedule the ultrasound appointment and called it my "sons lesion" Idk what the hell that means? God I am just terrified.
