Worst Migraine EVER

I've lived with migraines most of my life so the pain and side effects of them are nothing new. However on Tuesday I ended up with one like I have nI ever had before, and I find it hard to put into words everything that I had gone through.
On Monday morning I had gone to the doctor because of some more inflammation problems and was given an anti-inflammatory shot. I have been given this shot before and the past and while it had triggered migraines they where within my "normal" limits. But this time he gave me more then normal, and within 16 hours of that shot at 4:30am in the morning is when the migraine hit. I knew it wasn't normal from the start as bad as the pain was. Nothing worked from the start, prescriptions, herbals, hot, cold, ect... By 8am I was calling the doctors office to go get a shot so I wouldn't have to go to the ER.
It felt like I was trapped in my body and couldn't do anything, I remember what I did but have no real image of time. I know I called the doctors office 4 or 5 times, but how long in-between I have no idea. I remember my housemate driving me to the office but really have no idea how long it took. I mean I know it takes 30mins or so but it didn't feel that way. The best way I feel like I can somewhat put it, is that I kept passing out, but was awake the whole time. The vomiting was so forceful that it felt like it was going to come out both ends.
Now I find myself perhaps still in shock? And terrified.
I know I need to face my doctor and I wish I could say that I will NEVER have another anti-inflammatory shot again but I know that wish will never come true. I just don't know what to do when the next time comes. I also know that no matter what my doctor says he will never convince me that the shot and migraine were not linked. I also can't find anything online about this happening to anyone else, in fact it all says that anti-inflammatory stuff is suppose to help stop migraines. So again I feel lost and terrified.
