Unfortunately none of us here can tell you whether or not you have epilepsy since we aren't your doctors
A lot of us can tell you first hand that EEGs and MRIs can come back clear but you can still have epilepsy (me! lol), so I wouldn't base it off of that.
Like Critter said, your best bet is to call your doctor and tell them that you want an explanation. Don't be afraid- this is your health you're talking about and they are required by law to explain anything to you that you don't understand. Drs tend to be short with us because they're in a hurry and whatnot, but we have every right to ask questions about what we see- especially if it concerns a diagnosis you weren't even AWARE that you had!
As far as I know, you need to be notified of a diagnosis given to you at any point in time, whether it be by the Dr or nurse.
... yay, can you tell who's in training to work in a hospital? lol
