Thanks very much for all the feedback. No, my son got no meds at the ER (Kaweah Delta Hospital, Visalia, CA). His primary care physician (Kaiser - Northern CA) said he wouldn't consider regular meds until a 2nd seizure.
My son spent last week at home just taking it easy. He's worked out the bus schedule, and we drove him home yesterday. He'll have about a 5 block walk from bus stop to work, so we sure hope all goes well.
The neurologist is probably competant, but is just very ill mannered. Example, while giving my son some simple tests, he pointed at the back of his wristwatch and said, "What's this?" My son said it was a "clip". Neurologist rolls his eyes and says, "No, it's a clasp." There's are several neurlogists in this group, so we can just ask to change. Thanks for the suggestions on 2nd opinions. I will definitely do that if the tests come back with anything but all negative.
My wife and I keep trying to think of environmental factors that might have brought this on, in the say the 24 hours prior. Any benefit to dwelling on that, or is that usually fruitless?
Thanks again for the advice and the warm welcome.
