Sudden Severe Headache & Gastrointestinal Distress: What Could It Be?

Question
Hi!  I am hoping you can shed some light on this situation:  Sunday I had a mild headache all day.  It kept getting worse throughout the day and by dinner it was kind of bad.  But the wierd thing is that around 9pm it seemed to get out of control really fast.  The pain got real bad, I got sick to my stomach - came very very close to throwing up twice but never did.  I did have diareah twice.  But the thing that REALLY scared me was that my body started to shake uncontrollably.  I also was getting warm and clammy on and off.  Now, I have had migraines before but never been sick from them.  Although, I do know people get sick and throw up from migraine.  But the thing that really scared me was the body shaking.  I had no idea what was happening.  I have never heard of people having body shakes with migraines. I finally fell asleep hours later and when I woke up in the morning was pretty much fine!  It's just eating away at me now though - what it could have been.  Do you think all those symptoms could have been from a migraine?  Or something bad I ate? Or a bug?  Or something else?  Thanks for your insight!

Answer
Do you think all those symptoms could have been from a migraine? Not usually since has not done this before.

Or something bad I ate? This can start it but usually not continue beyond a few hours, think of preservatives or MSG.

Or a bug? Usually would last longer.

Or something else. Magnesium oxide deficiency can do this but check with your doctor
