Epileptic Seizures Query?

I’ve been on Carbamazepine for TN for a while now, and after a visit last week to my neuro, he’s replaced my Gabapentin with Pregabalin. Both these meds are prescribed for seizures associated with MS, plus pain control. The thought of seizures really scares me. Is anyone else on these two meds for ms seizures/pain control? Scary thoughts… :cry: Denise.
