Can pain cause my epilepsy seizures worse?

Possible: Anything that causes an increase in stress can lead to an increase possibility of seizure, it is more likely to increase seizures in post traumatic epilepsy but possible in idiopathic epilepsy as well.

Possibly: Any time there is something that stresses the brain, this can exacerbate the seizures and make them more difficult to control. For example, stress from fever, infections, lack of sleep are known to exacerbate seizures. Thus, pain can also do that.
