Lara,
Thanks for comments and support. Sam had his pituitary gland function checked with some bloodwork and other hormone levels were also checked. He had normal results. His serum 100 beta protein was on the normal/high side. He also had an MRI which did not reveal anything abnormal. He is in the classic PCS boat that is taking it's own time to clear. This summer he will start school stuff if symptom free at next appt.
