Maybe ignorance is bliss. LOL. I probably have had needles that were dull as they didn't go in on the 1st try. But I just assumed I chickened out towards the end and slowed down on my "dart" throw.

I always look at the medicine in the syringe before I inject. If it looks suspicious, I get a new one (letting it warm up 1st, of course).

Even though I have been on C for a couple of years now, my site reactions vary from time to time. Sometimes I will still get a larger welt that itches and is sore for a few days. There are areas that I always get reactions. Hence, I no longer do my thighs.

In the 2 years I have been on C I have only had 1 dreaded reaction. Although a little scary, I knew what it was and just relaxed until it passed.

Let us know what happens after you write that letter. I'd be interested in knowing what they say.
