I just used my first injection of Test Prop. last night, and this morning I woke up with pretty good amount of pain in the injection site which is the lateral deltoid. Is this fairly common with IM reactions? The injection site isn't swollen or nasty looking just the muscle underneath hurts almost like a pulled muscle. This is my first cycle and I took the time to make sure I did it right no airbubbles in the syringe and everything was clean. I just want to know if this is a normal reaction and about how long will it take for the pain to subside?
