Urination as a Seizure Trigger?

[JRuner]

I know this has been discussed a little along the line of UTI's. But almost consistently when I urinate I have hard upper body shakes or myoclonic right shoulder jerking sometime where I can barely stay sitting on the toilet (I used to house clean I even make my sons sit!). Is there a nerve stimulated when urinating that might trigger a seizure I drink tons of water and very rarely have UTI's. This happens almost every time I urinate. Sorry for sharing from the bathroom but its just weird!

Thanks
