Done that! When it happened, I wasn't sure if I pulled & cramped the opposite lat, or if I had partially dislocated the shoulder! BAD! Felt like I got stabbed with a sword though the back of the armpit and out through my shoulder. What I do now for rear head delt injections is to hold the syringe like a pencil to stick, then I hold it near the needle end with my thumb & middle finger; pushing the plunger with my pointer finger. That's the only way that works for me, and I can't reach to pin the rear heads at all the same day I work my delts.whats worse is pinning your own shoulder and you get a spasm in your opposite lat... holy shit
There's nothing wrong with hitting the front heads of your delts, as far as I know, but for me they hurt and I often get a bruise.
On quads, I go for midway from the knee to the hip, and straight sideways. There are arteries and nerve branches in the way if you pin in the front of the thigh, or on the back, so the outer side is the only safer way I have been told. It will be sore the next day; no way out of it. Just pin it only once in awhile, and deal with a little soreness. And the way it works for me, the more I pin a certain muscle, the less it hurts after awhile. My rear delts and glutes are totally painless now. I would think that if I did quads more, they'd also get immune to the pain.
