I got my first migraine in 2001 at age 31 right about the same time I developed persistent heart palpitations, or fluttering. My cardiologist ran some tests, couldn't find anything wrong, said it was probably mitral valve prolapse, and put me on Atenolol. My aura includes loss of vision, appearance of flashing, colorful broken glass and numbness on one side of my body. I've had about 20 migraines since that time, and every one scares the heck out of me. I tried Imitrex, Maxalt and Relpax, and none did anything for me. About three years ago, I discovered that Frova greatly limited the pain, even though it still left me with the other side issues of the migraine. Since migraine does not run in my family and I was completely headache-free throughout my childhood and young adult years, I'm obviously concerned about a misdiagnosis. Anybody got any ideas out there?
