Did the screaming occur at the time of the seizure? My senior had a seizure a couple of years ago during the middle of the night, and it was accompanied by "vocalization." It was the worst blood-curdling SCREAM I have ever heard, I couldn't believe that loud noise was coming out of that little dog. The vet never found out what was wrong, and it never happened again. The vet said it was involuntary, just like the stiffening and shaking, and it was not a response to pain. The dog doesn't even know that the seizure is happening or that they are vocalizing.
If the crying is happening when the dog is NOT seizing, then the poor thing is in pain.
