jmo but usually you arnt present when you have a seizure - so if you are aware its unlikely you are having a seizure -
tremors can be caused by a traumatic brain injury and there are meds that can stop that
ptsd does cause tremors - when I am triggered I shake - sometimes just hands somtimes body
maybe get it checked out by your dr and see what they say
take care

When you have come to the edge of all light that you know and are about to drop off into the darkness of the unknown,
Faith is knowing One of two things will happen: There will be something solid to stand on or you will be taught to fly.
