My daughter is a school bus driver who had her passenger endorsement suspended due to her going on insulin from Cushing's induced diabetes.  She had a pituitary microadenoma removed in November.  She has not had any insulin since the day before surgery and her blood sugar is stabilizing.  Now, she is being told that the D.O.T. considers any 'penetration of the dura' to lead to potential seizure risk.  We are trying to get whatever information we can on this subject.
