I’ve never had this problem before, but the last box of pens I got all seem to have the same issue. Pretty much any time I inject 4 units or less the pen gives me resistance as though it’s done while it’s still stuck on 1. If I release my thumb and try again, I can sometimes get it to finish the dose, but other times I have to pull the pen out before it will let me pop out that last unit.
I used to be terrible about priming every time; I’d just prime when I switched needles, which I don’t tend to do until they start to dull a bit. Now I’m changing needles and priming before every injection, which doesn’t seem to fix the problem anyway.
Anyone else experience this? Do I just have weak little girl hands, or have they made some change with the pen that’s making this more difficult?
