Hi Jolene. That sounds excruciating. and in my opinion sounds like a lot more than just chronic migraine is going on with you for sure. If your feet are blue it means a lack of oxygen to the area, you need an Emergency room immediately. If you live on top of a hospital? (as I think I read) I'd slap a mask on and go in anyway, or call an ambulance and go to a different one. That really does sound serious, and you shouldn't wait or question, just do it.
As for your obvious nerve pain, you need a specialist, I bet if they fix that part of you, you'll find alot of relief for your migraine troubles due to the stress and muscle stiffening and fatigue you'd experience with being so spastic.
This is just my opinion, and I am in no means a professional anything, anymore.
Good luck to you Jolene.
