thoughts and prayers on their way..
friend went through this back in '05. his was caught as a "pre-cancerous" tumor. around the right temple area.
out of nowhere he started having seizures. no history of them.
once the tumor was out, he did continue to occasionally have them for a couple years, but was mostly able to control them with medication.
there was at least one time in that period where the docs wouldn't let him drive, if he had a flair of seizures, they wouldn't allow him to drive for 6 weeks, as long as he remained seizure free during that period, they would let him resume driving.
he's Mostly normal now, well, 99% of where he was before, just has memory gaps,(for the couple years before the surgery), but can normally re-access the memories with a little work. (literally having to navigate new pathways)
be prepared for intense itching around the incision for a WHILE, as the nerves heal. you will want to scratch, but DO NOT!
