Vampire Cannula Redux.
Last week, my blood sugar numbers were great for a day and a half after a site change, but then they went off the rails. Untouchable 200s that no bolus would bring down and only exercise was able to budge. Usually, these stubborn highs are the fault of an infusion set issue, and sometimes I am just as stubborn as the highs, refusing to pull the site.
But this time, when I examined the site, I saw the pooling of blood, and figured there was a vampire cannula on tap. (See also: No kidding, because there normally isn't blood in the site.)
And within an hour of the new site, I was back in range. Funny how well insulin works, when it's able to get into your body. ;)
