My brother had a seizure earlier tonight. After getting hit in the head. He has epilepsy. He then went to the bathroom. And ended up having another one. And fell onto our tub. with his back. And continued seizing there. After we tried to move him to the floor. And he came out of the seizure. He stated he could not feel anything past his chest. And is in a great deal of pain from his back. Do you have any idea what could be wrong?
