I'm amazed that you had a management med that actually worked! I have tried four different kinds and none of them have worked for me. I also tried acupuncture and while I enjoyed it, I got NO relief from migraines.
I also tried chiropractic, but it didn't help at all, they wanted me to commit to a year's worth of treatment at $2,000, and when I googled chiropractic I really couldn't find any scientific validity for their claims. I know that tons of people say that chiro has helped them, and I really wish someplace reputable like the Mayo would do a study to see if chiropractic ideas have any truth to them, or if they are just hogwash.
I'm waiting to get clearance for Botox now, and I can't wait. I have migraines 14+ days a month and it is so hard.
Physical therapy really helped me during the month I had it -- I went in twice a week and got therapeutic massage and that month I only had one migraine. Massage or PT would probably be a really good thing to try.
