No, not normal. Based on reports from other pump users with similar
experiences, the problem usually has one of several possible origins.
1) Sensitivity to a component in a "prep" material or "tape" that
irritates the infusion wound. This is usually fixed by switching from
one type of tape to another or from one prep mfg to another, i.e.
Bards to Smith & Nephew or visa versa. Switching to a non-latex tape
such as IV3000 -- even that bothers some people and other tapes work
for them instead. There are some paper based tapes from 3m that work
in a pinch.
2) Sensitivity to the plastic material used in the cannula. Try
SofSets vs Sil/Tender/Comfort set -- or use Disetronic Rapids for a
3) Sensitivity to Humalog -- Try FIRST using straight regular or
Velosulin insulin to eliminate or confirm Humalog as the culprit. If
so, then try a mix of 5 parts H and 1 part V (or R).
4) You may be a "Staph" carrier. These little guys live in some
people's nasal cavities and are benign THERE, but cause serious
problems when they make their way into a wound. You can easily
be tested to confirm or refute this. Revised sterile field techniques
will eliminate this as a source of contamination. I won't review them
here at this time.
These options should be discussed with your health care provider.
Only ONE thing should be change at a time in your management regimen
so that you can clearly identify what has been eliminated when the
problem goes away. Changing two or more things at the same time makes
