I use the SureClick, too. Reminds me of years ago when I had to inject Imitrex for migraines. It had to be a really bad headache before I'd use that. OUCH! Then the neck pain within a minute or 2. But 15-30 minutes later, the headache was usually gone.
Was told that using an ice cube to numb up the area was useful. I did it once and that was the one time the injector misfired. Never tried it again. YMMV.
