Did your seizures stop after the surgery? Has the tumor or seizures returned at all?
In the last 6'ish years the pre-seizure aura (these are now called considered seizures of their own) have returned. I get perhaps 1 every 4 months (if I had to guess). I have been in contact with my Doctor & specialists to make sure it's not a tumor growing back. The specialist has informed me that it's common. If it becomes more frequent or severe in intensity then we can look into it doing something about it.
