Okay so I was diagnosed with epilepsy when I was 10 went on medication then at age 17 was taken off medication because I was seizure free for 2 years. I am now 24 and been seizure free from petite mal seizures for 7 years but 2 days ago I had a grande mal seizure which I have never had before. Could this be my epilepsy returning. What could of caused it? I don't drink, smoke or do drugs
