Hi,
Welcome to the forum! Take my word I've had veeg done along with many other tests over the past 35 yrs. of seizures. The veeg is painless and the only thing that might bother you is the cream might to start to dry and make your head itch but that's normal. You might want to take a book or some puzzles to do while having the test done because sometimes a person can get board.
As far as the neurophsyc. testing take my word I had it done before I had brain surgery and then after I had surgery. All you have to do is answer simple questions and the Dr. can tell what side of the brain you are using it's really interesting to me.
I've also had Pet, Spect, CT, and wada tests done. It's amazing what the Drs. can find by doing these tests and they don't hurt at all. Here's wishing you well and May God Bless You!

Sue
