Hi Rosa
I've had very similar experiences over time, some even a little more radical than what you've described. and have been practicing SFQ for 3 years.
They don't happen to me much these days and my Qi feels much more like a river flowing without too many obstructions in its path. When I did get the movements, I observed and felt them and believed that it was the qi doing its work and ridding me of energy blockages.
I don't suffer from seizures and wouldn't imagine from your explanation that you are either.
I say stay with it, trust it and know that your qi is working for you.
Love
Jetay
