I only have one child and she gets severe migraines that are proceeded by a visual aura (vision is severely affected) followed by extreme abdominal pain and nausea. As far as it relating to MG or a channelopathy, I would not know. I get a lot of headache but I attributed them to eyestrain trying to get the double vision back in focus.

Pleases let us know if the doctors attributed it to a channelopathy.
thanks
