I'm wondering if anyone else out there has to take Coumadin (blood thinner) on an ongoing basis, and also has Chronic Migraine? I do, & it VERY much limits the medications that I can take, either to prevent or treat the migraine. I've had 6 DVTs, Deep VeinThrombosis (clots), in my Right subclavian vein, so the doctors think I am too much of a risk to ever get off the Coumadin. I'm also on Plavix, which is another anti-coagulant (blood thinner), also for life. My first clot was in 1998, my most recent was in 2011. I've had surgery to remove the top rib on the right side, because it was thought that my collar bone (clavicle) was compressing the vein between it & the rib, causing the clots. Unfortunately, I've had 2 clots since that surgery, so that wasn't it. Sorry for getting into all the details. It just adds to the frustration of the migraines, is all. Thanks for listening.
