question: My son had his wisdom teeth removed this morning and was under general anesthesia. Upon waking he began having difficulty. He was hallucinating, and began having what was compared to a panic attack. This continued and the dentist then gave him Valium. He was transported to the ER where he was kept until he woke up on his own and did not have any other issues.  We brought him home and he slept for several hours. Upon waking, he took some pain meds, had a small snack and went back to sleep. He woke up about an hour later and when he got up to use the restroom, began having a full blown attack, with hyperventilation, and incoherent. The question that I have is, is this common? Why does this keep happening and what should we do?
