I don't know if this is similar, but often I lose hearing, it feels numb down the side of my face, neck and ear, and feels like a blockage, almost as if I have had dental work, and a siezure usually follows. I am wondering if this is similar to what your friend experiences?

I had epilepsy as a child then nothing for years, when I hit my 20's I had another 2 seizures, then nothing for over ten years; then it hit en force with one large seizure and a series of smaller ones, and then in reverse, small ones leading up to tc. Because the seizures don't follow a set pattern other than with the photosensitivity, it is difficult to pin what will happen.

The one thing I have learned about epilepsy is that it is fickle and having several types of siezures can be very confusing. Especially when siezures don't happen the day you have tests done.

I wish your friend all the best...
