I recently had a seizure and had an eeg but doctors aren't sure why. now i'm having these episodes where my legs and arms tremble badly. why?

Seizure: Sometimes people with epilepsy. An have normal EEG. Trembeling of arms and legs may be a feature of other issues like Anxiety . If the symptoms are not similar to the initial event , it is likely that it may not be a seizure. But I would suggest a follow up with your doctor screen you for other possibilities.

Uncertain: You may need to be referred to a neurology expert who deals with seizures. Often such physicians are at large medical centers.
