Re: [IP] Re: stinging sensation while bolusing

I had this problem all the years I pumped before velosulin became widely available.  It has only ever come back when I used just humalog in the pump for a week or so.  14 or 15 years ago, I was told the velosulin was revolutionary pumping insulin b/c it had some kind of buffer in it that reduced the irritation under the skin and eliminated the stinging and supposedly also kept the insulin from clotting as humalog can.  On the last point, people on the list have suggested that it does no such thing -- from a chemical analysis perspective.  It may not but it did help lots alleviate the stinging and discomfort and seemed to last longer in the pump syringe.  Who knows.  You might consider mixing the two types although I realize with Kayla's small doses that could get tricky.

This burning sensation has been reported by a number of Humalog users. I
experienced it for my entire time with Humalog (14 months) and know it's
not pleasant. I was able to deal with it for the most part by carefully
monitoring the angle and depth of the infusion set, as discussed. However,
despite all the attention I paid, I still ran into this on occasion. I just
think it's a characteristic of the insulin when infused.

I noted Ellen's post about splitting the bolus into multiple smaller
boluses. This works for some users, is worth trying. I used this trick with
"large" boluses (typically over 7 units) with mixed success.

This problem may not be limited to Humalog, but certainly seems to occur
with far less frequency for Velosulin or Regular users. Barb may have some
added info in this area. I have not had any problems with V stinging or

Disetronic should have their 6 mm Rapid infusion set available "soon", and
it may offer another possibility for thinner pumpers.

If Humalog bothers Kayla so much, it might be worth taking a look at
Velosulin or Regular, before returning to MDI. I don't suggest this
lightly, nor do I think you should make the change without giving it some
very serious thought, since it will involve re computing rates, procedures,
etc.. Kayla sounds like a real "trooper", but this could try her patience
(as well as yours). A pump "vacation", while you re consider things, is an
alternative as well.

This is roughly the point I got to with my Humalog struggles - I was ready
to pack it in and return to injections, but figured I owed it to myself to
at least give V another try. I had only used it for 4 months before
switching to Humalog in 1996. I'm glad I did this - it taught me that the
tool was the *right* tool, but the "fuel" was not the correct match for me ;-)
