My Boyfriend I Feel Has Had A Seizure. He Had

My boyfriend I feel has had a seizure. He had uncontrolled movement in his arms and legs. He was shaking for a short period of time..approx 30 seconds. He started with an uncontrolled cough. Then his head dropped back and his eyes rolled to the back of his head. I said his name several times and he didnt respond. I called for family members to help and he snapped out of it. He seems fine now but I am very concerned. What are you thoughts?
