I don't really see the need to pin it anywhere else than your glutes. It's not easy the first time but after that it's smooth sailing and it's still considered the best place for most injectable steroids. If you do it once a week and just switch glutes youre homefree.
Regardless though, if you inject anywhere try and keep the needle as stable as possible. As stated above the needle works as a blade and the more you move it (shake perhaps), the more it cuts when it's inside of your tissue. This causes pip. My first injection (not so long ago) hurt for two weeks because i shook like a little old man. Learned from that mistake
