32 year old male. Admitted to ER with A-Fib. Treated with lovenox and atenolol. Cardioverted 3 days later. The headaches began as soon as I started the coumadin and have persisted everyday since. Worked with doctor to find cause of headaches, tried switching blockers, no avail. The only other med I'm on is warfarin. What else could it be? I love how a quick search shows "coumadin, no known side effects", but here's a room full of people with the same headaches. Now I see, headaches are just the beginning. What kills me, is instead of finding out why I went into A-Fib, and working to fix the real problem, the doctor's would rather thin my blood, so I don't have a stroke when my A-Fib comes back! I refuse to poison myself to death, just to avoid death by stroke. Come get me, I'm done with this qwuap!
