First of all -  remember that it takes Botox 5-7 days to fully develop so sometimes at 3 days, for example, as it's taking effect, there can be a few funny sensations.  These almost always go away after a few days.  Let the Botox "settle in" for at least 10 days and then, if it's still happening, go back and talk to your provider.  Maybe one of your muscles is pulling a little unevenly when you raise your forehead.  If your symptoms seem to be getting worse, call and go see your doctor right away.  Dr. I
