No I haven´t.  This is my first cycle and I´m using Cyp.

I pinned both glutes, and right quad, today, is my 4´th pin in my left quad.
One of my glutes hurt like hell going in, as I guess I hit a nerve, but I just continued.
I am sore too for 2-3 days after pin.  But injecting into the muscle is the same as hitting it with a baseball bat.  To minimize the "bruise", inject very slowly.
