Yes, the headaches are so severe that he hasn't been able to work for a several weeks now, and is the reason that he went to the ER in the first place. The second time he went to the ER, he was admitted for extensive testing. MS is what they have found after ruling out everything else. He also has double vision episodes, and is losing his sight in his right eye, 20/120.
Thanks again for your prayers, and I will keep everyone updated as we find out more.
