Hi there I understand your frustration but you are going to have to be patient and give these different medications there own time to see what is right for your son. I was about 13 when I was going through a simular situation, now I am 37. It sounds like you are trying everything under the sun. This most likely will not vanish from his life, it is a matter of finding out what is going to be the best way to manage this in a way he can live normally. Doctor's are good but you need to do your own research to narrow his triggers and treat his life like a process of elimination for the time being. I have the sporatic hemiplegic migraines. For myself i have narrowed down my triggers and have symthoms prior to an attack in which I take a medication called Maxalt, I then take a 15 minutes to a half hour quiet break eyes mostly closed then I regain myself for the rest of the day. Before Maxalt I was disfunctional the rest of the day. I also found aggressive sports send my bloodvessels into a frenzy and almost immidiately after stopage the aura feeling starts and sends me into the cycle. I find a low impact treadmill excersise does allot for me. I wish you only the best I feel your pain, I really do. I agree with the other writer the emergency room is not the greatest place for your son, as a matter of fact it make make it worse with the lights noises and the anxiety factor. I don't know the severity of your son's condition but I can tell you I have learned to live with mine and have reached unconsciousness and been relieved by spinal tap at one point at its worst. So there is hope!
