I am scheduled for an MRI on Monday and I am really freaking out.. The eye doctors nurse made me feel like I may have tumor and I am automatically thinking the worst... They want to rule out a pituitary gland which the eye doctor himself made it sound like it was something simple but the nurse today made it sound like I was on my death bed... Any thoughts or advice.. I have been feeling lighted headed and for a while now my right hand cramps up and stays that way for a few seconds to maybe a minute. My sister automatically said that I could have a tumor due to someone she used to work with acted this way..
