So ya, my Sister is an EMT/Nurse and she does my injections for me. Which was kind of weird, but we are close so she is okay with it. She has been doing them in my legs, and now after a month the scar tissue has emerged. She just did one and you could hear it pop and hurt pretty bad, but it worked. I mean as long as it's on the side of my quad/leg and i can feel the muscle, would it be okay to inject there?
