Hi Maddie,
Well, let me give you the quickie lecture on how to do a painless and hopefully bruiseless shot. First off get the 30g penlet needles!! they are sooo tiny that they literally are painless. Next after you have one on your pen and its cocked and loaded, pinch up a bit of skin and touch the needle to it. If you feel a "prick" or an "ouch"..move to another spot. You may have to do this a bunch of times but eventually you find a spot that isn't "ouchy". At that point, put a little pressure on the pen and the needle should slip right in painlessly. If it hurts as you begin to push it in, stop and find another place to inject as the painfull area is full of nerves and may in fact leave a bruise.
I hold the penlet much like a pencil to get the needle in and then switch my hand around to grip the barrel the way they show you in the tutorials to push the button. I just find its much easier to manipulate the needle if Im holding it like a pencil.
Last but not least, when you are holding the button down and leaving the needle in for 5 seconds after the injection, DON'T push really hard on the button, you've already injected the stuff and all you are doing is puting tension behind the needle and potentially causing a bruise. Keep a gentle pressure on the button and keep the needle inserted but without a lot of force behind it! Hopefully this will help your bruising!
Also, Maddie, use a pattern that moves in a circle. Use your thighs as well as your belly so that you do left thigh, left side of stomach, right side of stomach, right thigh and then repeat. That way you aren't over stressing one particular area.
One last thought. There are "short" pen needles and there are "mini" pen needles. The "mini" are the shortest at about 3/8" so make sure you use these instead of the 1/2 inchers.
Oh, and just so you don't think that those of us long time users are immune, I had two plain donuts and a cup of coffee for breakfast and the carbs made me really queasy and nauseaous for about 3 hours so even after a year and a half the lizard bite can still get to me!
