goose bumps & 'hidden' seizures?

Hi, this is Maddie, I'm really glad to find this site. I still don't know for sure whether i have some kind of epilepsy. Neurology hasn't been much help, but my own dr believes i do because of a long history of strange episodes and LTL abnormality on eeg. But if so i don't understand exactly what form the seizures are taking, since those general episodes that i get can go on for a couple of days (seems too long for a single seizure, surely?). Also I don't have the main things that are often mentioned with left TLE, like bad smell, deja vu, staring, chewing, etc. (at least as far as I know). But over about 8 years I've steadily developed so many problems with mental speed, executive functions and any kind of abstract thinking, and i just can't understand how this much damage could be done by epilepsy - if that's what it is - wihtout seizures making themselves more obvious. Is there any such thing as sub-clinical seizures, or seizure-like activity, that can go on without classic seizure signs? Also, can goose-bumps be part of a seizure? Mine can be on leg, or head, or arm, or sometimes head & arm together, but only ever on one side at a time, never left & right together. The feeling can cover half or most of my leg or arm, but when I look at it the visible goose-bumps are spread out in a strange random pattern - say a blob here, a little curving strip there, and another patch further down. For a while they keep coming with a sort of 'pumping' feeling, like pulsing every few seconds. Also there's a 'soft' version of the same thing, that just makes a patch of skin feel a bit sticky. On days when I get all this it can be basically continuous, several times every hour. Can goose-bumps be an aura? Is an aura basically a simple partial seizure?
