Yes, Where is the article on treating seizures following stents? My friend has two stents in his heart and tonight he had 2 almost 3 seizures. But, from what people have said, the seizures happened before the stents. FYI: He is in constant pain needing a knee operation (scheduled for April 22, 2016/. He does not want anything to get in the way of this knee operation.
