It's not for me actually, I have a friend that has recently been in a car accident and has had a possible concussion. Although, they are not actually sure. She has had an MRI, CT scan, you name it, it's been done. Blood tests are amazing. They did however, say her Pituitary gland( near her nose or wherever) is enlarged. Other symptoms include: dizziness, fatigue, feeling nauseated. Doctors say no big deal but, symptoms are getting worse and she's at her wits end. She was, before all of this, a severe diabetic. ( insulin dependent) She has lost some unintentional weight. Sugar levels have "in a sense" corrected themselves! Impossible right? They have indicated there is nothing wrong with her. I am scared for her! I don't know what else to do.
