migraine
"I have suffered from migraines for 32 years, the older I am the worse they become. I have both the Imitrex pills & the shots.  When I am nauseated I must use the shot.  Approx. 1 minute after injection the intense buring in my head & the amplified headache are the worst side effects however NOTHING compared to the migraine.  Usually the migraine is gone in 15 - 30 mins and I sleep it off. There is also the 12 - 24 hour Imitrex hangover from the shot.  Muscles feel as though they are made of jelly, overall wiped out feeling.  The pill does not have the burning effect for me and it takes the full 30 minutes to combat the migraine.  Imitrex is the only medicine which has worked for me consistantly over the years.  I become immune to all other  medicines."
