Thank you for bringing me into this discussion!
@juda I have epilepsy myself and exercise daily - whether it's walking, playing tennis, or doing Pilates. Regular physical activity is actually known to potentially improve seizure control and reduce some side effects of anti-seizure medications. So I really doubt that your son's exercise with his left hand triggered this seizure.
I'm not a doctor, but I suspect something else may have triggered this seizure. A few questions: Did he experience any stress that day or the day before? How was his sleep? Both stress and poor sleep are well-known seizure triggers. Also, was anything changed in his medication before this seizure occurred?
If I understand correctly, this was his first seizure? That must have been quite frightening for both of you.
I'm sharing an article from the Epilepsy Foundation that covers common triggers - you might find it helpful as you and your son start identifying what to watch for:
