My daughter has a Hemangioma above her right eye and her eye waters a lot too!!! My docs wouldn't order an MRI to confirm that the tear duct was affected, but it doesn't take a rocket-scientist to figure that one out
I am scheduled to have her H removed by Dr. Waner in May.
Best of luck to you, go see a specialist (even if it means traveling), and get insurance approval if necessary. The specialist will be the one to tell you if your child is a candidate for treatment.
