migraine
"I have Celiac disease and one of the side effects are migraines that use to last 3 or days until I found DHE 45 which was 1st done by IV.  After that I was prescribed the shots until the nasal spray came out. 



After 15 years of research on my own I have come to the conclusion that either Celiac or other allergens are the prime cause of migraines that last more then 24 hours and maybe those as well;  for these conditions cause swelling in every cell in the body including the neurons.



I hope this helps others who suffer from the debilitating pain caused by these episodes."
