migraine
"Imitrex pills worked for me for a few years but then it stopped being as effective and I had to take 2...  Then that stopped working so I tried Imitrex statdose (the injections) and they work wonders.  They hurt a lot but the pain in my leg after I give it to myself is far less horrible than the migraine pain!  I give myself the shot and lie down for about 15 minutes and I'm fine!  Maybe a little pain but I feel much better!  I'm also on Timolol, Neurontin, and Cymbalta and my migraines have reduced in number and then this helps when I get them.  And the shot works after you've had the migraine for a while - you don't have to take it at the first sign to get relief."
