Hi sheds,
I've had many seizures when changing AED's (meds) this is always normal and it can be a pain for some people.
If you fell out of bed while at the hospital and you are now having headaches and more seizures the hospital should be liable for all of this. If I were in your place I would speak to a lawyer and make sure that the hospital pays for all the medical bills and any other possible medical problems since they didn't put the rail up on the bed. If you live in the U.S. you should call The Epilepsy Foundation of America at 1-800-332-1000 they can give you good advice for free. I wish you the best of luck and May God Bless You!
