my son has complex partial seizures but I believe he had a tonic clonic while sleeping last night.. He was having a very off day yesterday.. He explained it like he felt very dulled.. He had trouble remembering the days events also.. when he woke up this morning his muscles were so sore he had trouble getting up there was also blood on his pillow.. Thinking he might have bit his tongue.I'm not sure if it was a tonic clonic or not but its the only thing i can think of to explain it.. I'm not sure what to think..
