I’m not only vain, I’m a guitarist and a programmer, so sore, bruised fingers are not an option. These are tricks I’ve learned:
Use a new lancet every time. They’re clean, sharp, have no burrs and they will make a hole that is just the right size to get the job done. Others disagree, they go for the punch of a blunt lancet. That makes the hair on the back of my neck stand up. I guess I spent too much time looking through my Daddy’s microscope as a child. (Eeek.)
Think of your finger tips as having four test “sites” each, e.g. with your right ring finger facing you, two on the left side of the top finger section, and two on the right side of the top finger section (one just beside the lower third of the nail, and one about a quarter inch below that, keeping clear of the joint). This is not the finger pad, but on the sides above the joint. If you have four per finger/thumb, then that’s forty possible test sites.
I rotate through them, trying to never re-use a site until I’ve used all forty. If you have tiny hands or fragile pinky fingers, you might not be able to get more than two “sites” per pinky, one on the left and one on the right. My “babies” are super sensitive, so not only do I only use one, central site on each pinky-side, I also dial back the pressure on my clicker to the lowest setting.
Even if you test ten times a day, you shouldn’t have to hit the exact same spot any more often than once every three to four days, plenty of time for healing. If a spot looks red or inflamed, go around it and give another rest.
Another trick I’ve learned is this: as soon as I put the drop of blood on the test strip, I press firmly over the test site with a clean paper towel or Kleenex . Pressing prevents a large amount of perfusion under the skin and diminishes the chance of any soreness/bruising. My hands were a mess until I figured this out: press on it – for at least ten seconds, fifteen is better.
One final trick: warm your hands really, really well in medium-hot water before testing. I just let the water run a little longer when I wash them, or else I’ll test them after hand-washing a few dishes and then rinsing them really, really well with warm water. Swinging them helps, too. If your hands are nice and juicy (full of blood) then the test droplet will just about leap out of your skin with the clicker on a very low setting. No squeezing! When you squeeze, you’re not only increasing the bruising, you’re diluting your test droplet with interstitial fluid (from between the cells), which generally runs about 20 minutes behind changes to your blood glucose. Squeezing results in tests that might not reflect the true value of your blood glucose. During rapid changes, this could throw you off.
I used to bruise all the time. Now the only time I bruise is when I forget to dial back the pressure on the clicker for my pinkies.
