It looks like my daughter may have inherited more than just my brilliance and good looks.  She has had a few incidents that made me wonder, but tonight she displayed all of the symptoms that I'm all too familiar with. 
I've had these since I was 18 or so, episodic, I'm 45 now, and am fortunate to get relief from O2, and keep imitrex on hand for the few that get through those.
I remember the long road to a proper diagnosis that I had, and don't look forward to her having to go through the tests, and docs that don't get it.
I'm not in cycle now, and don't have oxygen on hand, but was thinking about calling my most recent neuro (who is amazing by the way) and getting some more for her to try.  I wouldn't dare give her imitrex without a doctors approval of course, but didn't know if there was any danger to letting her try oxygen should she get another one. 
Are there any dangers I should worry about?  Any different flow rate or other instructions?
