Regarding the posting on a problem with static migraines:
Allow me share my experience with the mother of all static migraines. about 8 years ago I was hospitalized for 8 days with a migraine that would not relinquish its grip, despite multiple intravenous drug treatments, a spinal tap, and a spinal patch. The last 2 being extreme measures due to the fact the numerous doctors and neurologists that were exposed to by case were baffled. If it wasn't for the prescription drug Zomig, I don't know how long it would have continued. I have never been at such a low point in my life, before or since.
The doctors who were treating me never attempted this drug, but my wife had recalled that while we were living in Germany some years before, a doctor had prescribed this drug for recurring headaches. This drug is manufactured by a US firm, it is not some hard to get prescription, but it is fairly costly.
After I had given up, my wife contacted the German Doctor who had seen me some 5 or 6 years prior. She was reminded of the name of the medication, and my Doctors agreed there was nothing to lose. Hospitalization over.
For the next couple years I never traveled anywhere without access to a Zomig pill. I believe the active ingredient is called triptan, or that family of drugs. I'm clearly not a medical professional, and I can't speak to the root cause, but I know of the monster that is a true static migraine, and that medication was a life saver to me.
We had some issues with getting insurance to pay fairly regularly for that medication, but eventually they understood without it I could be susceptible to a recurrance, and another $15,000 hospitalization.
I know every case is different, but when you are in that situation, all that matters is getting the monster to release its grip.
Good luck. Incidentally, I've been migraine free for a number of years. I pursued some TMJ therapy not long thereafter that episode, and the root cause of my episode may or may not have been related. You may want to investigate that also. I was a teeth grinder, and was told I had very poor jaw alignment. Who knew. Again, while typically TMJ therapy is not covered, we refused to take no for an answer, and my insurance eventually came on board to cover my TMJ care.
