Hello all. Its just a general comment, and probably says more about me than anything, but I find this all quite fascinating. I have migraine since i was six years old, about 40 years. My understanding was that the cause of migraine is very poorly understood. Since that first diagnosis, I think I have only contacted a GP once about them, and that was to try a different drug, when I had a spell of my usual not working very well. I normally use Migraleave, as I get lots of visual warning usually, and if i catch with 10-20 seconds I can usually stop it or at least make it less vile. On the occasions that it comes in too big, or I don't get the pills down quickly enough, then it's a full-on whopper, and I'm out of commission for days. It has never occurred to me that i should pursue a scan or other treatment, as I thought this was pointless! Food for thought.
