Mine have changed since childhood. I started at about 6. My dad had them, so they had a bit of background for diagnosis. My sisters both get them, and now my son (diagnosed at 3, would wake from a nap and say, "my head hurts. Mommy, why do you have spots all over you?") Have done the brain scan thing with no obvious problem. Tried multiple different long-term meds. None was really effective. A cocktail of Immitrex, Fiorinal and tylenol #3 knocks most of them down to a liveable state. I've gone off the meds cold turkey to make sure the headaches weren't rebound. Worst month of my life. People who don't get them have very little clue what it is like to live from headache to headache. I feel like Jekyl and Hyde or some odd manic depressive. Non-headache days are almost an event to celebrate.
My biggest triggers are atmospheric changes, over exposure to sun/bright lights, and allergy/sinus problems.
The doctor would like me to continue to try new remedies, but the downside is playing with side effects for a couple of months at a time to see if it works. Currently, I function, hold down a good job, and seldom miss work. My onset has evolved over the past 30+ years. I use to get migraines everytime I had a deadline or other stressful event. Now, I get the headache with the let down after completion. Makes it much easier to get things done. Duration use to be 3-4 days. Now, it is seldom more than 1. I use to throw up repeatedly. Now, seldom. At this rate, they should be pretty much gone in another 20 years or so. There is an advantage to losing elasticity in the brain's blood vessels...
My aura has evolved to a point where I just start to lose peripheral vision. when I have to turn my head to see anything not directly in front of me, it is time to hit the meds. I go through about 3-4 headaches a week, with clusters that are worse, followed by 4-5 days when I don't have to take anything.
btw-how many people with migraines here have had at least one doctor label them "drug seeking"? I had it happen once. In retrospect, he was right, but not in the way he thought. I'd have taken anything to make that headache go away...
Whoa, this thread opened the floodgates for me...
