I've never had a problem with glute shots - no pain, veins, or nerves. Today, I was surprised when I used my typical 23g x 1.5" pin and it hurt like hell as I put it in. I aspirated, and for the first time ever, drew in a bunch of blood. To be honest, I was glad to see aspirating actually pay off, but I was surprised to hit a vein in my ass. Is that common to his veins in the glutes?

Also - what's up with the pain in the ass when I've never had that before?
