hereditary angioedema
"I am an unusual case in that I started experiencing attacks before I could walk.  I swell more frequently and severely than any other member of my considerably large family.  Unfortunately, Firazyr has provided minimal relief. It has slowed the onset of swelling, but did not stop it all together. That being said, I am grateful for any relief I can get during an attack, so I would encourage everyone to try Firazyr to treat their own episodes."
