pain
"I had come down with a very bad sinus infection that caused me to have a migraine like headache.  It was extremely unbearable.  So I had my spouse take me to the emergency room and the doctor gave me a shot in the rear and within seconds I felt immense relief.  The next day the headache came back and after eight hours of dealing with it, I went back to the ER and got another shot.  It was fabulous and it allowed me the ability to keep down my antibiotic so I could kick the sinus infection.  I don't know why they don't make an injection pen for Migraine sufferers to keep around.  Worked way faster than Imitrex ever did for me in the past."
