Oh dear lord, I've never met such a bunch of scared ass little girls.
Grab a fukkin 18ga and pin it. You will never complain about a 23ga again.
I've been pinning for 30+ years and cant not tell you the amount of scar tissue I have. A slin pin wont do it anywhere but the stomach for me.
Hell I pinned with a 25ga last week and had to re-pin in the calf. It just would not go into the delt and cracked the whole time. Then when I tried to punch the plunger it wouldnt budge, not a damn bit. Lol
So I switched pin top and pinned the calf. I can still pin the general areas if I use a 23, like delta, glutes and quads but anything smaller is just difficult. Now pinning calf, pec, bicep or other minor areas, no issues still.
I do use a 27ga when I pin the stomach though, always subQ in that area of course.
