Hi Stacy you are having a Myclonic Seizure. I have them they are really quick, & sometimes you don't even know you're having it. I hope I answered your question clearly.

If you are reactioning on one side then your seizures are coming from the other side. For example if your right side is on the right side then your seizures are coming from the left side. My brain surgery was on the left side and I was talking to the surgeon while he was operating on me.

Does this seizure on the one side in a quick rhythmic shake, with feeling of shock, and cause a clumsiness sometimes? If so sounds to be a (type) Myoclonic - (form) Focal seizure. If the effects its causing are always on the same side, it's a Focal seizure, which has multiple types of seizures. Also, the most common form seizures.

Document it. I've found my memory has gotten worse in the past 6 months since my diagnosis.
Best wishes 🙏

I also agree it could be myoclonic seizures.
The current medication I take has relieved me o seizure activity for the past four years.
Before that I would have twitches in my right hand at the same time like clock work.
Then they would disappear for few weeks and then return again.
Have a blessed day
