migraine
"Unfortunately after taking my first dose of Zomig, I had an allergic reaction to it.  Upper lip felt like I was stung by a bee and started to swell up on one side.  This stayed in the same location for about 45 minutes.  After that, my left cheek started to swell and get numb along with my nose.  Off to the ER I had to go.  While it DID kick the migraine, I had an unfortunate reaction to it."
