atrial fibrillation
"Flecainide has controlled the a-fib, but I have a constantly cold nose and my mouth feels like I've had lidocaine sprayed like before dental work.  Some days it's worse than other days.  I take 100 mg twice a day with 25mg metropolol.  After two cardioversions, I'm willing to give flecainide a chance.  I've been taking it for six months and hope the side effects don't get worse with time."
