Well, any seizure should be a trip to your doctor. Do you have a seizure disorder? I guess you are saying you don't have a diagnosis but are treated for seizures? I've read about triggers for an epileptic seizure but you don't sound to have been diagnosed with epilepsy. Massage of the head is actually a soothing treatment for seizures, believe it or not. Maybe you've discovered a trigger point which does happen (but usually with epilepsy). When can you visit your doctor again?
