my eye doc found something behind my eye causing pressure to my optic nerve. i went through three consults with neurosurgeons for tests such as ct\'s, mri\'s and multiple eye tests. one doc told me it was a brain tumor until ruled out. finally after the last specialist, he determined after an ultrasound that all i had was calcium deposits causing the appearance of pressure on the optic nerve. this can\'t be good either, can it? i still have nauseating headaches and numbness to my fingers and arms at times. but he did say it was not pseudo tumor cerebri. should i still be concerned?
