Lump at injection site? Need help

[Ranger32]

Been running tri-test, and deca . Very clean and hygenic. It's good stuff have had no problems from the 5 weeks prior. I usually have my wife inject me for ease, but I did my last one. I'm three days after my injection and in the shower I felt a lump right at the spot where I injected, I little pain, but no big deal, and you can actually see a small red area on my ass where I injected as well. Is this because I was shaking and moving the pin around when I injected by myself and just aggravated tissue? Infection? or is it normal to have a lump with an injetion sometimes from a bad stick? please help getting worried

Normal reaction to a less than perfect stick, you will be fine.

keep an eye on it, if it starts to get worse go to the doctor to get some antibiotics and it will go away.
