Hey there,
Involuntary crossing of the eyes is called strabismus. Although, I am not sure that is the proper term for what you endured. Also, it is not uncommon that something like 7/10 people will have 1 seizure in their lifetime. I pray that it is your one and only. Seeing as it is a nervous system problem and you are having migraines as well, have you ever thought about chiropractic? There have been thousands of patients that have responded well to care with migraines and other nervous system disorders. Chiropractic is NOT only about back and spine pain, as much as it is about making sure that the nervous system is working at 100%.
