Hi and again welcolme to the site
i got an instruction video with my first pack
and yes giving it by myself the first time was scary
virtualerror is right you Hold the Button down while you count
one other thing Before you give the injection put an ice pack on the site for a while
i used my thigh - easy to reach
by using the ice Before injecting it lessons any sting
by holding button down for the full 10 second count ensures you get the proper dose
When you say you think you screwed up the injection - why what happened
and you have to be careful don't go giving yourself another injection just incase you actually didnt muck it up
i'd phone my rhumy and check just what you should do, it may be safer to wait till next one is due
try not to get overwhelmed try to get hold of the instruction video go to the web site and watch it
Good Luck
