Chronic migrane sufferer help!!!!

 I have suffered from migranes Since the age of 16. i have had mri, spinal tap, x-ray, cat scan. all show negative. but the pain is very real. i am tripitan resistant. have tried most if not all the migrane medications. my doctors are giving me strong pain meds, and i am building a dangerously high tolerance. i go to the e.r. 1 to 2 time a month and get to listen to them explain how the e.r. is not a pain management clinic, when it is the pain management clinic that told me to go. And then i get the these medications are highly addictive, but everything else doesn't work. they can't answer that. Please all who read this any helpful advice, anything  would help. 

I AM SORRY TO SAY THAT I WAS ACTUALLY PLEASED TO READ YOUR MESSAGE.  I HAVE NOT HAD MIGRAINES IN THE PAST BUT SOMETHING HAPPENED AND MY HEAD HAS BEEN TERRIBLE SINCE THE BEGINNING OF APRIL AND THE DOCTORS HAVE NOT BEEN ABLE TO FIND ANY WAYS TO RELIEVE THE PAIN.  I HAVE GONE THROUGH ALL OF THE TEST YOU MENTIONED AND NOTHING.  HAVE YOU FOUND ANY HELP?  DID YOU RECIEVE ANY INSIGHT THAT WAS HELPFUL.  I AM NOW AT A POINT OF DEPERATION.  THEY JUST STARTED SOME STEROIDS BUT MY HEADACHES ARE WORST AFTER I TAKE THEM.  I AM OFF OF ALL OF MY PAIN MEDICATION AND AM about TO LOOSE MY MIND.  NOW, I CAN'T EVEN SLEEP SO I DON'T KNOW WHAT TO DO. 

I HOPE YOU HAVE FOUND SOME RELIEF AND SOME PEACE OF MIND (LITERALLY)  ANY INFORMATION YOU CAN GIVE ME I WILL THANK THE LORD FOR!

TAKE GOOD CARE OF YOURSELF AND TRY AND BE HEALTHY!
