Your being a pussy. Nah, I'm just fucking with you. A couple things could have went wrong. You moved around too much during your inject, you used the same needle to inject with that you drew with and a couple other things. Just make sure that it doesn't get too hot or red or you get a fever. I'm sure it's a little hot a red now but when it gets bad enough to go to the doc, you'll know. Youi also didn't mention what brand of gear you were using or if it was the first time you used it. I have done a couple cycles where every shot hurt like a bitch (it was almost always from QV Enan). I have also got done with an inject and knew right away that I was gonna be sore because I moved the needle around too much because I was stretching to reach the spot on my glute that I was raching for. If you injected too high on your quad that could also be a reason that your sore up to your tailbone. Injecting up real high on your quad can make you sore up above your tailbone sometimes. Hope something in here helps.
