I did my first Sustanon 250 shot on 4/12. My buddy put the needle in my right shoulder just above the tricep. The problem is that my arm is almost not useable and throbs with pain to the point of sleepless nights. I can hardly raise it over my head. So today I noticed that its red all around the shot area probably covering 4 to 5 inches in a circlular pattern and swollen slightly. Is this normal? Should I shoot the next one somewhere else?
