My daughter has suffered years with a cyst larger then a golf ball, that displaces her left hesphere and is groving her skull. The nurologist says her sever headaches cant be caused by cyst. Her nurosurgeon told me that Im just looking to have my daughters brain hacked on. I beleive fully that this cyst is the only logical cause for her pain. Do these cysts grow? Ive read they can rupture, though both dr`s told me it wouldnt and couldnt.
